## Color schemes
{: .d-inline-block }

{: .label .label-green }

Just the Docs supports two color schemes: light (default), and dark.

To enable a color scheme, set the `color_scheme` parameter in your site's `_config.yml` file:

#### Example
{: .no_toc }

```yaml
# Color scheme currently only supports "dark" or nil (default)
color_scheme: "dark"
```
<button class="btn js-toggle-dark-mode">Preview dark color scheme</button>

<script>
const toggleDarkMode = document.querySelector('.js-toggle-dark-mode');
const cssFile = document.querySelector('[rel="stylesheet"]');
const originalCssRef = cssFile.getAttribute('href');
const darkModeCssRef = originalCssRef.replace('just-the-docs.css', 'dark-mode-preview.css');

jtd.addEvent(toggleDarkMode, 'click', function(){
  if (cssFile.getAttribute('href') === originalCssRef) {
    cssFile.setAttribute('href', darkModeCssRef);
  } else {
    cssFile.setAttribute('href', originalCssRef);
  }
})
</script>

## Specific visual customization

To customize your site’s aesthetic, open `_sass/custom/custom.scss` in your editor to see if there is a variable that you can override. Most styles like fonts, colors, spacing, etc. are derived from these variables. To override a specific variable, uncomment its line and change its value.

For example, to change the link color from the purple default to blue, open `_sass/custom/custom.css` and find the `$link-color` variable on line `50`. Uncomment it, and change its value to our `$blue-000` variable, or another shade of your choosing.

#### Example
{: .no_toc }

```scss
// ...
//
// $body-text-color: $grey-dk-100;
// $body-heading-color: $grey-dk-300;
$link-color: $blue-000;
//
// ...
```

_Note:_ Editing the variables directly in `_sass/support/variables.scss` is not recommended and can cause other dependencies to fail.
