No way around that, other than removing the tag. Those two values will cascade (1.2 x 1.2) and that list item will be bigger in font-size than any of the others. Looks great for you today, but tomorrow some content is published to the site that has a paragraph inside a list item.

For example, you might set both your “p” (paragraph) and “li” (list item) font-sizes to be 1.2em. If you are using em’s as a straight substitution for pixel values, this can cause problems. Every em value is relative to its parents value. There is one potential concern with em’s, with regards to #3. That exact proportional relationship makes em values a powerful web design technique. If you have a box that is 10em in height, and a font inside that is 1em in size, it will take up exactly 1/10 the height of that box.

Em’s have a direct relationship to each other in this way. Elastic width sites use em values for everything, which essentially makes the site “zoomable”, meaning that when you bump the font-size up everything bumps up all the way down to the width of the site. If you basically want to use pixels but don’t like the accessibility problems, em’s may be the ticket for you.Įm’s aren’t just for fonts, it’s a unit of measure that you can use for any other length (height, width, etc).

The relationship to other sizes (elastic width sites).

So why both with all this em business when it’s just an abstraction of using pixel values anyway? Three possible reasons: This way, you need a font size of 18px? Use font-size: 1.8em. Using 10 as a multiplier is much easier than using 16. Because the default browser font-size is 16px, this makes it 10px (without hard-setting it to 10px, which wouldn’t cascade). The most popular method in working with em values is to set the font-size on the body to 62.5%. That math works out cleanly, but you can imagine that it often doesn’t and rounding needs to take place. So if the current em size is 16px, that header tag is going to turn out to be 32px. You can apply a “keyword”, like p That “2” is essentially a multiplier of the current em value. When it comes to setting the size of type in CSS, you have lots of options.
