There is no sentence caps option in CSS. The other answers suggesting text-transform: capitalize
are incorrect as that option capitalizes each word.
Here’s a crude way to accomplish it if you only want the first letter of each element to be uppercase, but it’s definitely nowhere near actual sentence caps:
p {
text-transform: lowercase;
}
p::first-letter {
text-transform: uppercase;
}
<p>THIS IS AN EXAMPLE SENTENCE.</p>
<p>THIS IS ANOTHER EXAMPLE SENTENCE.
AND THIS IS ANOTHER, BUT IT WILL BE ENTIRELY LOWERCASE.</p>
