CSS Properties

Panorama supports a subset of the HTML5 CSS properties, and also adds a number of custom CSS properties. Panorama has tried to follow the W3C spec when possible: searching the web for a property by name is often a good resource.

The most up to date list of panorama properties can always be found by running the "dump_panorama_css_properties" command. That will print out the full list of properties including their documentation.

Supported pseudo-selectors

:hover - mouse is over the panel
:focus - panel has keyboard focus
:active - panel is being actively used (mouse-down on the panel)
:disabled - panel is disabled
:enabled - panel is enabled
:inspect - panel is being inspected by the debugger
:selected - panel is selected (button checked)
:descendantfocus - a descendant of the panel has keyboard focus
:parentdisabled - a parent of this panel is disabled, thus implicitly disabling it
:layoutloading - panel is in-progress loading it's layout file and thus may want to display specially
:layoutfailed - panel failed to load requested layout file, and thus may want to display specially
:activationdisabled - panel is disabled for activation, may still be enabled for focus (normal disabled disallows all input/focus)

background-blur

Sets the amount of blur to apply to the contents behind this panel during composition. Default is no blur, for now Gaussian is the only blur type and takes a horizontal standard deviation, vertical standard deviation, and number of passes. Good std deviation values are around 0-10, if 10 is still not intense enough consider more passes, but more than one pass is bad for perf. As shorthand you can specify with just one value, which will be used for the standard deviation in both directions and 1 pass will be set.

Examples:

background-blur: gaussian( 2.5 );
background-blur: gaussian( 6, 6, 1 );

background-color

Sets the background fill color/gradient/combination for a panel.

Examples:

background-color: #FFFFFFFF;
background-color: gradient( linear, 0% 0%, 0% 100%, from( #fbfbfbff ), to( #c0c0c0c0 ) );
background-color: gradient( linear, 0% 0%, 0% 100%, from( #fbfbfbff ), color-stop( 0.3, #ebebebff ), to( #c0c0c0c0 ) );
background-color: gradient( radial, 50% 50%, 0% 0%, 80% 80%, from( #00ff00ff ), to( #0000ffff ) );
background-color: #0d1c22ff, gradient( radial, 100% -0%, 100px -40px, 320% 270%, from( #3a464bff ), color-stop( 0.23, #0d1c22ff ), to( #0d1c22ff ) );

background-color-opacity

Sets the background color opacity for a panel (does nothing on its own, but when merged with a full background-color it overrides the opacity).

Examples:

background-color-opacity: 0.5;

background-image

Comma separated list of images or movies to draw in the background. Can specify "none" to not draw a background layer. Combined with background-position, background-size, background-texture-size and background-repeat values.

Example:

background-image: url("file://{images}/default.tga"), url( "file://{movies}/Background1080p.webm" );

background-img-opacity

Sets the Opacity of background-image

Examples:

background-img-opacity: 0.5;

background-position

Controls the horizontal and vertical placement of the background image, with the format: <left|center|right> <horizontal length> <top|center|bottom> <vertical length>

If length is a percent, the specified location within the image is positioned over that same specified position in the background. If the length is pixels, the top left corner is placed relative to the provided alignment keywords (left, bottom, etc.). See examples for more details.

If 1 value is specified, the other value is assumed to be center. If 2 values are specified, the first value must be for horizontal placement and the second for vertical.

Examples:

// aligns the top left corner of the image with the top left corner of the panel (default)
background-position: 0% 0%;

// centers the image within the background (same as "center center")
background-position: center;

// aligns the bottom right corner of the image with the bottom right corner of the panel (same as "100% 100%")
background-position: right bottom;

// the top left corner of the image is placed 10px to the right of, 40px below the top left corner of the panel
background-position: left 10px top 40px;

background-repeat

Controls if the background should be repeated in the horizontal and vertical directions.

Possible values per direction:
"repeat" - (default) Repeated in the specified direction until it fills the panel
"space" - Repeated as many times as required to fill the panel w/o being clipped. Space is added between images to to align first and last image with panel edges.
"round" - Repeated as many times as required to fill the panel w/o being clipped. The image is resized to align first and last image with panel edges.
"no-repeat" - Not repeated

Possible single values:
"repeat-x" - equals "repeat no-repeat"
"repeat-y" - equals "no-repeat repeat"

Examples:

background-repeat: repeat; // equals "repeat repeat" (default)
background-repeat: repeat space; // repeats horizontally, spaces vertically 
background-repeat: no-repeat round; // 1 column of images, scaled to fit evenly

background-size

Sets the horizontal and vertical dimensions used to draw the background image. Can be set in pixels, percent, "contains" to size down to panel dimensions or "auto" preserves the image aspect ratio. By default, set to "auto" which preveres the image's original size.

Multiple background layers can be specified in a comma separated list, which are then combined with background-image, background-position, background-texture-size and background-repeat values.

Examples:

background-size: auto; // same as "auto auto" (default) 
background-size: 100% 100%; // image fills the panel
background-size: 50% 75%; // image fills 50% of the panel's width, and 75% of the panel's height
background-size: 300px 200px; // image is drawn 300px wide, 200px tall

background-texture-size

Sets the size used for generating textures from vector graphics (.svg files), default is -1 which takes the size from the svg file.

Example:

background-texture-size: 100px 50px; // width 100px, height 50px

blur

Sets the amount of blur to apply to the panel and all it's children during composition. Default is no blur, for now Gaussian is the only blur type and takes a horizontal standard deviation, vertical standard deviation, and number of passes. Good std deviation values are around 0-10, if 10 is still not intense enough consider more passes, but more than one pass is bad for perf. As shorthand you can specify with just one value, which will be used for the standard deviation in both directions and 1 pass will be set.

Examples:

blur: gaussian( 2.5 );
blur: gaussian( 6, 6, 1 );

Examples:

border-width: 1px;'
border-width: 20px 1px 20px 1px;

box-shadow

Specifies shadows for boxes, or inset shadows/glows. The shadow shape will match the border box for the panel,so use border-radius to affect rounding. Syntax takes optional shape 'inset', 'fill', or 'hollow', then color, horizontal offset pixels, vertical offset pixels, blur radius pixels, and spread distance in pixels. Inset means the shadow is an inner shadow/glow, fill is a a shadow behind the entire box, hollow means clipping it to outside the border area only (before offset). A negative blur radius will give a hard-edged look to the shadow, effectively a rounded outline of the same size as the blur.

Examples:

box-shadow: #ffffff80 4px 4px 8px 0px; // outer, filled
box-shadow: hollow #ffffff80 4px 4px 8px 0px; // outer, hollow
box-shadow: inset #333333b0 0px 0px 8px 12px; // inner

Sets the brightness that applies to the panel and all it's children during composition. The value is a multiplier on the HSB brightness value.

Example:

brightness: 1.5;

clip

Specifies a clip region within the panel, where contents will be clipped at render time. This clipping has no impact on layout, and is fast and supported for transitions/animations. Radial clip mode takes a center point, start angle and angular width of the revealed sector.

Example:

clip: rect( 10%, 90%, 90%, 10% );
clip: radial( 50% %50, 0deg, 90deg );

color

Sets the foreground fill color/gradient/combination for a panel. This color is the color used to render text within the panel.

Examples:

color: #FFFFFFFF;
color: gradient( linear, 0% 0%, 0% 100%, from( #cbcbcbff ), to( #a0a0a0a0 ) );

context-menu-arrow-position

Specifies where to point the arrow of a context menu at on this panel. The first value controls how the arrow is positioned horizontally when the context menu is to the top or bottom of the panel, and the second value controls how the arrow is positioned vertically when the context menu is to the left or right of the panel. Default is '50% 50%'.

Example:

context-menu-arrow-position: 25% 50%;

context-menu-body-position

Specifies where to position the body of a context menu relative to this panel. The first value controls how the body is aligned horizontally when the context menu is to the top or bottom of the panel, and the second value controls how the body is aligned vertically when the context menu is to the left or right of the panel. 0% means left/top aligned, 50% means center/middle aligned, and 100% means right/bottom aligned. Default is '50% 50%'.

Example:

context-menu-body-position: 50% 100%;

context-menu-position

Specifies where to position a context menu relative to this panel. Valid options include 'left', 'top', 'right', and 'bottom'. List up to 4 positions to determine the order that positions are tried if the context menu doesn't fully fit on screen. Default is 'right left bottom top'. If less than 4 positions are specified, the context menu first tries the opposite of the specified position along the same axis before switching to the other axis.

Examples:

context-menu-position: bottom;
context-menu-position: left bottom;

contrast

Sets the contrast that applies to the panel and all it's children during composition.

<pixels> - Any fixed pixel value (ex: "100px")
<percentage> - Percentage of parent height (ex: "100%")
"fill-parent-flow( <weight> )" - Fills to remaining parent width. If multiple children are set to this value, weight is used to determine final height. For example, if three children are set to fill-parent-flow of 1.0 and the parent is 300px tall, each child will be 100px tall. (ex: "fill-parent-flow( 1.0 )" )
"width-percentage( <percentage> )" - Percentage of the panel's width, which allows you to enforce a particular aspect ratio. The width cannot also be height-percentage.

horizontal-align

normal - no manual spacing
<pixels> - Any fixed pixel value (ex: "1px")

line-height

Specifies the line height (distance between top edge of line above and line below) to use for text. By default this is 'normal' and a value that matches the font-size reasonably will be used automatically. Unlike the web, we don't have a weird CSS inheritence problem with the 120% vs 1.2 styles.

Example:

line-height: normal;
line-height: 20px;
line-height: 1.2;
line-height: 120%;

margin

margin-bottom

"squish" - Children are squished to fit within the panel's bounds if needed (default)
"clip" - Children maintain their desired size but their contents are clipped
"scroll" - Children maintain their desired size and a scrollbar is added to this panel

"noclip" - Children maintain their desired size and content is allowed to overflow this panel

Examples:

overflow: squish squish; // squishes contents in horizontal and vertical directions
overflow: squish scroll; // scrolls contents in the Y direction

padding

padding-bottom

padding-left

padding-right

padding-top

perspective

Sets the perspective depth space available for children of the panel. Default of 1000 would mean that children at 1000px zpos are right at the viewers eye, -1000px are just out of view distance faded to nothing.

Example:

perspective: 1000;

perspective-origin

Sets the perspective origin which will be used when transforming children of this panel. This can be thought of as the camera x/y position relative to the panel.

Example:

pre-transform-rotate2d: 45deg;

pre-transform-scale2d

Sets 2 dimensional X/Y scale factors that apply to the quad for this panel prior to 3 dimensional transforms. This scaling applies without perspective and leaves the panel centered at the same spot as it started. Default of 1.0 means no scaling, 0.5 would be half size.

Examples:

pre-transform-scale2d: 0.8
pre-transform-scale2d: 0.4, 0.6

saturation

Sets the amount of saturation to apply to the panel and all it's children during composition. Default of 1.0 means no adjustment, 0.0 means fully desaturated to gray scale, greater than 1.0 means over-saturation.

text-overflow

Controls truncation of text that doesn't fit in a panel. "clip" means to simply truncate (on char boundaries), "ellipsis" means to end with '...', and "shrink" means lower the font size to fit. "noclip" allows the text to overflow based on the "overflow" style.
"shrink min( 10px )" won't shrink beyond a minimum font size, clipping the overflow. "shrink min( 10px ) ellipsis" is similar but will ellipsis the overflow.

We default to ellipsis, which is contrary to the normal CSS spec.

Examples:

text-overflow: ellipsis;
text-overflow: clip;
text-overflow: shrink;
text-overflow: shrink min( 10px );
text-overflow: shrink min( 10px ) ellipsis;
text-overflow: noclip;

text-shadow

Examples:

tooltip-position: bottom;
tooltip-position: left bottom;

transform

Sets the transforms to apply to the panel in 2d or 3d space. You can combine various transforms (comma separated) and they will be applied in order to create a 4x4 3d transform matrix. The possible operations are: translate3d( x, y, z ), translatex( x ), translatey( y ), translatez( z ), scale3d( x, y, z), rotate3d( x, y, z ), rotatex( x ), rotatey( y ), rotatez( z ).

Examples:

transition: position, transform, background-color;

transition-timing-function

Specifies the timing function to use for transition properties on this panel, if more than one comma delimited value is specified then the values are applied to each property specified in 'transition-property' in order. If only one value is specified then it applies to all the properties specified in transition-property. Valid timing functions are: ease, ease-in, ease-out, ease-in-out, linear.

Examples:

transition-timing-function: ease-in-out;
transition-timing-function: ease-in-out, linear;
transition-timing-function: cubic-bezier( 0.785, 0.385, 0.555, 1.505 );

ui-scale

Specifies a scale to apply to this panel's layout and all descendants. This scale happens at the layout level ratherthan the bitmap level, so things like text will increase their font size rather than just bitmap scaling.

Examples:

ui-scale: 150%; // 150% scaling for X, Y, and Z.
ui-scale: 50% 100% 150%; // 50% scaling for X, 100% for Y. 150% for Z.

ui-scale-x

Specifies a scale to apply to this panel's layout and all descendants. This scale happens at the layout level ratherthan the bitmap level, so things like text will increase their font size rather than just bitmap scaling.

Examples:

ui-scale: 150%; // 150% scaling for X, Y, and Z.
ui-scale: 50% 100% 150%; // 50% scaling for X, 100% for Y. 150% for Z.

ui-scale-y

Specifies a scale to apply to this panel's layout and all descendants. This scale happens at the layout level ratherthan the bitmap level, so things like text will increase their font size rather than just bitmap scaling.

Examples:

ui-scale: 150%; // 150% scaling for X, Y, and Z.
ui-scale: 50% 100% 150%; // 50% scaling for X, 100% for Y. 150% for Z.

ui-scale-z

Specifies a scale to apply to this panel's layout and all descendants. This scale happens at the layout level ratherthan the bitmap level, so things like text will increase their font size rather than just bitmap scaling.

Examples:

ui-scale: 150%; // 150% scaling for X, Y, and Z.
ui-scale: 50% 100% 150%; // 50% scaling for X, 100% for Y. 150% for Z.

vertical-align

visibility

Controls if the panel is visible and is included in panel layout. Possible values:
"visible" - panel is visible and included in layout (default)
"collapse" - panel is invisible and not included in layout

wash-color

Specifies a 'wash' color, which means a color that will be blended over the panel and all it's children at composition time, tinting them. The alpha value of the color determines the intensity of the tinting.

Example:

wash-color: #39b0d325;

white-space

Controls white-space wrapping on rendered text. "normal" means wrap on whitespace, "nowrap" means do no wrapping at all.

Examples:

white-space: normal;
white-space: nowrap;

width

Sets the width for this panel. Possible values:
"fit-children" - Panel size is set to the required size of all children (default)
<pixels> - Any fixed pixel value (ex: "100px")
<percentage> - Percentage of parent width (ex: "100%")
"fill-parent-flow( <weight> )" - Fills to remaining parent width. If multiple children are set to this value, weight is used to determine final width. For example, if three children are set to fill-parent-flow of 1.0 and the parent is 300px wide, each child will be 100px wide. (ex: "fill-parent-flow( 1.0 )" )
"height-percentage( <percentage> )" - Percentage of the panel's height, which allows you to enforce a particular aspect ratio. The height cannot also be width-percentage.

world-blur

Sets the amount of blur to apply to the world / backbuffer before drawing.

Examples:

world-blur: gaussian( 2.5 );
world-blur: gaussian( 6, 6, 1 );
world-blur: mipmapgaussian( 6, 6, 4 );  In this version each gaussian pass is preceded by a quarter area downsample.

x

Sets the x, y, z position for a panel. Must not be in a flowing layout.

Example:

position: 3% 20px 0px;

y

Sets the x, y, z position for a panel. Must not be in a flowing layout.

Example:

position: 3% 20px 0px;

z

Sets the x, y, z position for a panel. Must not be in a flowing layout.

Example:

position: 3% 20px 0px;

z-index

Sets the z-index for a panel, panels will be sorted and painted in order within a parent panel. The sorting first sorts by the z-pos computed from position and transforms, then if panels have matching zpos zindex is used. z-index is different than z-pos in that it doesn't affect rendering perspective, just paint/hit-test ordering. The default z-index value is 0, and any floating point value is accepted.

Example:

z-index: 1;
