![]() ![]() ![]() a pair of numbers in curly braces ( ) indicates that the preceding type, word, or group occurs at least A and at most B times.īox model Box model Dimensions width: | auto. ![]() The width and height specifies the size of the element. If width is not specified, the width is based on the width of the element’s contents. If height is not specified, the height is based on the height of the element’s contents. The alternative box model that USS uses is different from the standard CSS box model. In the standard CSS box model, width and height define the size of the content box. An element’s rendered size is the sum of its padding, border-width, and width / height values. Unity’s model is equivalent to setting the CSS box-sizing property to border-box. UI Toolkit includes a layout engine that positions visual elements based on layout and styling properties.

Positioning /* The default value is `relative` which positions the element based on its parent.

Unity reduces border radius values to half of the element’s size in pixels The smallest unit in a computer image.Unity doesn’t support the second-radius shorthand ( border-radius: (first radius values) / (second radius values) ) used to create elliptical corners.For detailed information about border-radius, see the MDN documentation. Pixel size depends on your screen resolution. Pixel lighting is calculated at every screen pixel. For example, for a 100px x 100px element, any border-radius value greater than 50px is reduced to 50px. If you use percentage ( %) values for border radius properties, Unity first resolves the percentage to pixels and then reduces the border-radius value to half of the resolved pixel value. If you have different radius values for two or more corners, Unity reduces any values greater than half of the element’s size to half of the element’s size.
