Creating Simple Text Effects With CSS

With CSS, we can create some pretty interesting text effects that are a great way to focus on typography. And now with webkit, we’re able to style the stroke property of the text, which is definitely a step-up from simple text-shadows.

I’ve been experimenting with CSS text effects over the past few days to create various effects. You can view the demo below, or download the source files for more info. Most of the effects use either “text-shadow“, pseudo classes “before” and “after“, or “-webkit-text-stroke“. Let’s run through a quick example.
