Pseudo-elements select part of an element. In this video, learn to use the four most commonly used pseudo-elements correctly, including before, after, first-line, and first-letter.
- [Instructor] Pseudo-elements look like … pseudo-classes but they're much lower … in specificity, more like an HTML element selector. … They change a part of a selected element … but not the whole element as most selectors do. … Some pseudo-elements are written in two forms … of syntax and specifically the four I cover here … are affected by this. … There are pseudo-elements that were introduced … in CSS two where they were written with a single … colon so they look like pseudo-classes. … But in CSS three they changed the pseudo-element … syntax to two colons so you don't have to remember … whether a pseudo-element supports one or two colons. … Just be safe and write 'em all with two colons … going forward. … There are several pseudo-elements available … to you but I'm going to focus on the four … with the best support and that are probably the most used. … And so the first one I want to talk about … is the first letter construct. … And so first letter will take the first letter, … say of this paragraph, and style it in some special way. …
