Learn what CSS Inheritance means and why it's important

When you set some properties on a selector in CSS, they are inherited by all the children of that selector.

I said some, because not all properties show this behaviour.

This happens because some properties make sense to be inherited. This helps us write CSS much more concisely, since we don’t have to explicitly set that property again on every single children.

Some other properties make more sense to not be inherited.

Think about fonts: you don’t need to apply the font-family to every single tag of your page. You set the body tag font, and every children inherits it, along with other properties.

The background-color property, on the other hand, makes little sense to be inherited.

Properties that inherit

Here is a list of the properties that do inherit. The list is non-comprehensive, but those rules are just the most popular ones you’ll likely use:

I got it from this nice Sitepoint article on CSS inheritance.

Forcing properties to inherit

What if you have a property that’s not inherited by default, and you want it to, in a children?

In the children, you set the property value to the special keyword inherit.

Example:

body {
	background-color: yellow;
}

p {
  background-color: inherit;
}

Forcing properties to NOT inherit

On the contrary, you might have a property inherited and you want to avoid so.

You can use the revert keyword to revert it. In this case, the value is reverted to the original value the browser gave it in its default stylesheet.

In practice this is rarely used, and most of the times you’ll just set another value for the property to overwrite that inherited value.

Other special values

In addition to the inherit and revert special keywords we just saw, you can also set any property to:

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching May 21, 2024. Join the waiting list!
