Re: Corner Tab – CSS Tricks

[clokey2k]

He uses the CSS-Triangle trick, and uses ::before psuedo element to add, and rotate, to any ‘article’ or ‘.turned-corner’ elements.

It took me a while to work the triangle trick out. If after reading the article it doesn’t make sense imagine the triangles point being the centre of a box with no bottom border, a coloured border across the top, and 2 transparent borders on the left and right.
