Got to love Vertical rhythm
One way to spot an inexperienced webdesigner or UX designer as they’re called now is if they don’t know about vertical rhythm. I for one love it. and I found a nifty website to help me with it.
It lets you select fontsize and lineheight and the scale factor.
AND GIVES YOU THE CORRESPONDING CSS :o.
If find vertical rhythm massively important to give you a visual knowledge of what goes together with what. And this website is just a little help.
