all

Definition

The all function is a CSS function that is used to apply a style rule to all elements. It is used as a shorthand for the * selector, which selects all elements in a document.

Examples

/* set the font size for all elements to 16px */
all {
  font-size: 16px;
}

/* reset the margin and padding for all elements */
all {
  margin: 0;
  padding: 0;
}

/* set the background color for all elements to white */
all {
  background-color: white;
}

It's important to note that the all function is not widely supported in browsers, and it is not recommended for use in production code. Instead, it is generally better to use more specific selectors to apply styles to specific elements.

For example, instead of using the all function, you could achieve the same effects as the examples above using the * selector like this:

/* set the font size for all elements to 16px */
* {
  font-size: 16px;
}

/* reset the margin and padding for all elements */
* {
  margin: 0;
  padding: 0;
}

/* set the background color for all elements to white */
* {
  background-color: white;
}

This code has the same effect as the examples using the all function, but it is more widely supported by browsers.

Value

The all function does not accept any values. It is a CSS function that is used to apply a style rule to all elements, and it is used as a shorthand for the * selector, which selects all elements in a document.

Best Practices

1. Avoid using the all function in production code: The all function is not widely supported in browsers, and it is not recommended for use in production code. Instead, it is generally better to use more specific selectors to apply styles to specific elements.
2. Use the * selector as an alternative: If you need to apply a style rule to all elements, you can use the * selector as an alternative to the all function. The * selector is widely supported in all modern browsers, and it is a more reliable choice for production code.
3. Use more specific selectors whenever possible: In general, it is better to use more specific selectors to apply styles to specific elements rather than using the all function or the * selector. This helps to improve the performance of your stylesheets and makes your code easier to maintain.
