How to Create Dynamic Theme-Driven Color Customization Using Sass Variables?

Leveraging Dynamic Sass Variables for Theme-Driven Color Customization

In Sass, you can set color variables differently based on the classes applied to HTML elements, enabling you to create dynamic, theme-driven styling.

Let's examine how to achieve this using conditional Sass syntax:

<code class="scss">html {

  &.sunrise {
    $accent: #37CCBD;
    $base: #3E4653;
    $flat: #eceef1;
  }

  &.moonlight {
    $accent: #18c;
    $base: #2a2a2a;
    $flat: #f0f0f0;
  }
}</code>

In this example, Sass will set the color variables $accent, $base, and $flat dynamically based on the presence of the sunrise or moonlight class on the element.

Another technique involves modifying the CSS file dynamically based on a given theme. Using CSS includes, you can import different theme-specific styles into your main stylesheet:

<code class="scss">_theme.scss:

section.accent {
    background: $accent;
}

.foo {
    border: $base;
}

.bar {
    color: $flat;
}</code>

<code class="scss">main.scss:

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

    @import "theme";
  }

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

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

By dynamically adjusting the values of color variables, you can effortlessly create tailored color schemes that adapt to different themes or user preferences.
