84. How to create triangles with CSS?

As an AI language model, I can provide a few approaches to creating triangles using CSS:

  1. Using borders: You can create a triangle shape by manipulating the border property of a div element. For example, setting the width and height of an element to 0 and then setting the border property to only specify one edge.

  2. Using pseudo-elements: You can use the ::after or ::before pseudo-elements to create a triangle by setting a width and height of 0 and then specifying only one border. Then you can rotate the element using the transform property to make it a triangle.

  3. Using SVG: You can also create triangles with SVG format, which can be embedded into HTML using an tag. You can define the coordinates for the triangle points and fill it with color or even use gradients.

These are just a few ways to create triangles with CSS, there are many more techniques and tricks depending on the use case.
