CSS text-transform: Uppercase, Lowercase, Capitalize (With Examples)

Many developers search for “uppercase to lowercase CSS” expecting real conversion. CSS can only change how text looks, not the underlying value. This guide explains the difference and shows when CSS is appropriate.

Table of contents:

text-transform: lowercase

This makes text appear in lowercase, but the original string is unchanged. 
.selector { text-transform: lowercase; }

text-transform: uppercase

This makes text appear in uppercase without modifying the source string. 
.selector { text-transform: uppercase; }

text-transform: capitalize

Capitalize makes the first letter of each word uppercase, again only visually. 
.selector { text-transform: capitalize; }
