How can Sass Variables be used to Create Dynamic and Themed CSS Styles?

Dynamic Styling with Sass Variables

Setting color variables in Sass based on HTML element classes can enhance the flexibility and responsiveness of CSS code. This article explores a solution rooted in the concept of theming.

One approach involves utilizing Sass includes to define multiple themes within a single CSS file. This allows for easy switching between themes:

<code class="scss">// _theme.scss
section.accent {
    background: $accent;
}

.foo {
    border: $base;
}

.bar {
    color: $flat;
}

// main.scss
html {
  &amp;.sunrise {
    $accent: #37CCBD;
    $base: #3E4653;
    $flat: #eceef1;

    @import "theme";
  }

  &amp;.moonlight {
    $accent: #18c;
    $base: #2a2a2a;
    $flat: #f0f0f0;

    @import "theme";
 }
}</code>

Alternatively, a Sass mixin can be created to simplify the theming process further:

<code class="scss">@mixin theme($accent, $base, $flat) {
    // ... define styles based on the provided colors ...
}</code>
