What unit of measurement should I use for

line-height?

Many designers rely on ems to set line height.

Because the exact size of an em is dependent on the

font size, using ems for line height ensures that the

height scales with the font. You can use decimals to

set fractional line height, so for example 1.5 ems sets

the line height to one and a half times the text size.

What is the advantage of using text-transform for

headings? Can I just not type the heading using

the correct case?

Large sites may have many people adding content,

and you cannot always control how they type the

content. Using text-transform guarantees that

headings use consistent casing.

● When viewed in a browser,

the main heading on the page

has the text transformation

applied, and the paragraphs

have the line height.
