Drawing Trapeziums with CSS3
Creating trapezoids with CSS3 requires some clever techniques. Despite the suggestion of using CSS3 3D transform, we explore a modern method utilizing CSS Transform Perspective.
CSS Transform Perspective
The CSS Transform Perspective property introduces a 3D space for elements, allowing them to rotate around a specified perspective. By applying a perspective value to an element and then rotating it along one of the axes (X, Y, or Z), we can create the illusion of a trapezoid.
Example
Consider the following CSS code:
.trapezoid { width: 200px; height: 200px; background: red; transform: perspective(10px) rotateX(1deg); margin: 50px; }
HTML:
<div class="trapezoid"></div>
In this example, the element with the class .trapezoid is configured with a width and height of 200 pixels, a red background, and a transformation that applies a perspective of 10 pixels and a rotation of 1 degree along the X-axis.
The resulting element will appear as a trapezoid with a slightly skewed top and bottom. The effect becomes more pronounced as the perspective value increases.
