## CSS-Variables

This theme is highly customizable because many aspects are parameterized with CSS variables.

To give you an idea of how flexible the styling is, click this button:

<div class="primary-button" onclick="toggleThemeVariant()" onkeypress="if (event.keyCode == 13) toggleThemeVariant()" tabindex=0>Alter theme</div>

<br><hr>

### Setup

It is recommended to add your own `custom.css` and override the variables there:
```
HTML_EXTRA_STYLESHEET  = doxygen-awesome.css custom.css
```

Make sure to override the variables in the correct place. All variables should be customized where they have been defined, in the `html` tag selector:

```css
html {
    /* override light-mode variables here */
}
```

For dark-mode overrides, you have to choose where to put them, depending on whether the dark-mode toggle extension is installed or not:

<div class="tabbed">

- <b class="tab-title">dark-mode toggle is installed</b>
    ```css
    html.dark-mode {
        /* define dark-mode variable overrides here if you DO use doxygen-awesome-darkmode-toggle.js */
    }
    ```
- <b class="tab-title">dark-mode toggle is **NOT** installed</b>
   The dark-mode is enabled automatically depending on the system preference:
    ```css
    @media (prefers-color-scheme: dark) {
        html:not(.light-mode) {
            /* define dark-mode variable overrides here if you DON'T use doxygen-awesome-darkmode-toggle.js */
        }
    }
    ```

</div>

### Available variables

The following list provides an overview of the variables defined in [`doxygen-awesome.css`](https://github.com/jothepro/doxygen-awesome-css/blob/main/doxygen-awesome.css).

The list is not complete. To explore all available variables, have a look at the CSS starting from [here](https://github.com/jothepro/doxygen-awesome-css/blob/main/doxygen-awesome.css#L30).
All variables are defined at the beginning of the stylesheet.

## Doxygen generator

The theme overrides most colors with the `--primary-color-*` variables.

But there are a few small images and graphics that the theme cannot adjust or replace. To make these blend in better with
the rest, it is recommended to adjust the [doxygen color settings](https://www.doxygen.nl/manual/customize.html#minor_tweaks_colors) 
to something that matches the chosen color scheme.

For the default color scheme, these values work out quite well:

```
# Doxyfile
HTML_COLORSTYLE_HUE    = 209
HTML_COLORSTYLE_SAT    = 255
HTML_COLORSTYLE_GAMMA  = 113
```

## Share your customizations

If you have customized the theme with custom colors, spacings, font-sizes, etc. and you want to share your creation with others, you can do this [here](https://github.com/jothepro/doxygen-awesome-css/discussions/13).

I am always curious to learn about how you made the theme look even better!
