  Customize colors, fonts, and more for your site.
---

By default, a site using Docsy has the theme's default fonts, colors, and general look and feel. However, if you want your own color scheme (and you probably will!) you can very easily override the theme defaults with your own project-specific values - Hugo will look in your project files first when looking for information to build your site. Also because Docsy uses Bootstrap 4 and SCSS for styling, you can override just single values in its special SCSS project variables file, or do more serious customization by creating your own versions of entire SCSS files.

## Color palette and other styles 

To quickly change your site's colors, add SCSS variable project overrides to `assets/scss/_variables_project.scss`. A simple example changing the primary and secondary color to two shades of purple:

```scss
$primary: #390040;
$secondary: #A23B72;
```

* See `assets/scss/_variables.scss` in the theme for color variables etc. that can be set to change the look and feel.
* Also see available variables in Bootstrap 4: https://getbootstrap.com/docs/4.0/getting-started/theming/ and https://github.com/twbs/bootstrap/blob/v4-dev/scss/_variables.scss

The theme has features suchs as rounded corners and gradient backgrounds enabled by default. These can also be toggled in your project variables file:

```scss
$enable-gradients: true;
$enable-rounded: true;
$enable-shadows: true;
```

{{% alert title="Tip" %}}
PostCSS (autoprefixing of CSS browser-prefixes) is not enabled when running in server mode (it is a little slow), so Chrome is the recommended choice for development.
{{% /alert %}}

Also note that any SCSS import will try the project before the theme, so you can -- as one example -- create your own `_assets/scss/_content.scss` and get full control over how your Markdown content is styled.

## Fonts

The theme uses [Open Sans](https://fonts.google.com/specimen/Open+Sans) as its primary font. To disable Google Fonts and use a system font, set this SCSS variable in `assets/scss/_variables_project.scss`:

```scss
$td-enable-google-fonts: false;
```

To configure another Google Font:

```scss
$google_font_name: "Open Sans";
$google_font_family: "Open+Sans:300,300i,400,400i,700,700i";
```

Note that if you decide to go with a font with different weights (in the built-in configuration this is `300` (light), `400` (medium) and `700` (bold)), you also need to adjust the weight related variables, i.e. variables starting with `$font-weight-`.

## CSS utilities

For documentation of available CSS utility classes, see the [Bootstrap Documentation](https://getbootstrap.com/). This theme adds very little on its own in this area. However, we have added some some color state CSS classes that can be useful in a dynamic context:

* `.-bg-<color>`
* `.-text-<color>`

You can use these classes, for example, to style your text in an appropriate color when you don't know if the `primary` color is dark or light, to ensure proper color contrast. They are also useful when you receive the color code as a [shortcode](/docs/adding-content/shortcodes/) parameter.

The value of `<color>` can be any of the color names, `primary`, `white`, `dark`, `warning`, `light`, `success`, `300`, `blue`, `orange` etc.

When you use `.-bg-<color>`, the text colors will be adjusted to get proper contrast:

```html
<div class="-bg-primary p-3 display-4">Background: Primary</div>
<div class="-bg-200 p-3 display-4">Background: Gray 200</div>
```

<div class="-bg-primary p-3 display-4 w-75">Background: Primary</div>
<div class="-bg-200 p-3 display-4 mb-5 w-50 w-75">Background: Gray 200</div>

`.-text-<color>` sets the text color only:

```html
<div class="-text-blue pt-3 display-4">Text: Blue</div>
```

<div class="-text-blue pt-3 display-4">Text: Blue</div>

## Customizing templates

### Add code to head or before body end

If you need to add some code (CSS import or similar) to the `head` section on every page, add a partial to your project:

```
layouts/partials/hooks/head-end.html
```

And add the code you need in that file. Your partial code is automatically included at the end of the theme partial [head.html](https://github.com/google/docsy/blob/master/layouts/partials/head.html) (the [theme version](https://github.com/google/docsy/blob/master/layouts/partials/head.html) of `head-end.html` is empty):


Similar, if you want to add some code right before the `body` end, create your own version of the following file:

```
layouts/partials/hooks/body-end.html
```

Any code in this file is included automatically at the end of the theme partial [`scripts.html`](https://github.com/google/docsy/blob/master/layouts/partials/head.html).

Both `head.html` and `scripts.html` are then used to build Docsy's [base page layout](https://github.com/google/docsy/blob/master/layouts/_default/baseof.html), which is used by all the other page templates:

```html
<!doctype html>
<html lang="{{ .Site.Language.Lang }}" class="no-js">
  <head>
    {{ partial "head.html" . }}
  </head>
  <body class="td-{{ .Kind }}">
    <header>
      {{ partial "navbar.html" . }}
    </header>
    <div class="container-fluid td-default td-outer">
      <main role="main" class="td-main">
        {{ block "main" . }}{{ end }}
      </main>
      {{ partial "footer.html" . }}
    </div>
    {{ partialCached "scripts.html" . }}
  </body>
</html>
```
