Design a responsive site with em-based sizing You've probably heard that you should use relative units for font size. This is a good rule for accessible web design; if the user changes their browser's default font size, this enables your page's text to resize accordingly. You may have taken this advice and made the switch. Perhaps you got out your calculator and converted your site's font sizes from absolute px units to ems or, more likely, rems. But if that's where you stopped, you are missing out on a lot of the flexibility and power that ems bring to the browser.

One problem that arrises when you use inline-block is that whitespace in HTML becomes visual space on screen. Gross. There are a few ways to remove that space; some of them are just as gross, one is reasonably nicer. Solution 0: No Space Between Elements
