Join James Williamson for an in-depth discussion in this video Generated content, part of CSS: Selectors.
- One of the more interesting capabilities of CSS…is generated content.…That is, using the pseudo element selectors…before and after to inject content directly…before or after the existing content of an element.…Now since this content exists outside the DOM,…it's typically used for decorative or non-essential uses.…Now before we experiment with this,…I'm gonna take a look at the syntax.…I'm gonna scroll down into this generated.htm file.…You can see both of the examples here before and after…used the pseudo element selector syntax…of the two colons instead of just the one.…
Although as we discussed before,…older browsers supported the single colon syntax…so there's no harm in doing it that way…and most people are still doing it that way.…Okay now in this case in the syntax…when you use either the pseudo element selector…of before or after, you're also going to use…a property value that is distinct to it,…and that is the content property value.…Now content is gonna be what it is…that you're injecting either before or after…
