In this section you can add CSS and Javascript to further customize the appearance of your docs site.
## Custom Stylesheet
You should limit your changes to minor tweaks. Additionally, stylesheets aren't versioned; all versions use the same stylesheet.
## Custom Javascript
Your Javascript will be included at the bottom of the page.
<details> <summary><b>Global Variables</b></summary>
ReadMe exposes certain global variables to help you customize the user experience of your hub:
**`
RM_ReferenceSidebarScrollTopOffset`** Pixel offset for the scroll-to-active-item sidebar logic in continuous <<glossary:Reference>> sections.
</details>
## Custom Include Tags
**Header HTML**
Any html here will be included in the head tag, which is good for things like meta tags and loading external CSS or JS.
**Footer HTML**
This will go right before the `</body>` tag. Good for things like analytics and tracking.
## Toggling Custom Javascript and CSS
Add the `?disableCustomCss=true&disableCustomJs=true` query params to the end of any URL.
