# CSS Types
CSS types define the values that Textual CSS styles accept.
CSS types will be linked from within the [styles reference](../styles/index.md) in the "Formal Syntax" section of each style.
The CSS types will be denoted by a keyword enclosed by angle brackets `<` and `>`.
For example, the style [`align-horizontal`](../styles/align.md) references the CSS type [`<horizontal>`](./horizontal.md):
--8<-- "docs/snippets/syntax_block_start.md"
align-horizontal: <a href="./horizontal/"><horizontal></a>;
--8<-- "docs/snippets/syntax_block_end.md"
