CSS triangle also known as cascading style sheets triangle is a way to create graphical triangles on
a webpage using CSS without the help of images or svg.
Methods of creating CSS triangles:
- Using Borders: This is a classical way of creating triangles in which an empty box (with
zero width and height) is created and the borders are styled to form the triangle.
- About the borders: One border is solid and colored which determines the triangle shape
and the remaining two borders are transparent. Width and positioning of the border are adjusted
to create different orientations of the triangle like Upwards, downward, right or left.
- Using clip path: This is a new approach that uses clip path property for the exact shape
of the triangle. It is comparatively more smoother and flexible.
Advantages of Using Borders over clip-path

advantages:

are supported widely
