## Good to know

## IntelliSense for CSS class names in HTML

A Visual Studio Code extension that provides CSS class name completion for the HTML class attribute based on the definitions found in your workspace or external files referenced through the link element. Download here.

## CSS Hyphens

The Hyphens property controls hyphenation of text in block level elements. You can prevent hyphenation from happening at all, allow it, or only allow it when certain characters are present. For more details see css-tricks.com.

> Note: Hyphens is language-sensitive. Its ability to find break opportunities depends on the language, defined in the lang attribute of a html element. Not all languages are supported yet, and support depends on the specific browser.
