Using accent-color for Simple User Interface Theming in CSS

The CSS accent-color property is used to set the accent color for form elements and controls such as checkboxes, radio buttons, range inputs, and progress bars. This property helps in providing a consistent theme to your user interface with minimal effort.

Checkboxes

<style>
  input[type="checkbox"] {
    accent-color: red;
  }
</style>

<input type="checkbox" id="checkbox" checked />
<label for="checkbox">Accept</label>

Radio buttons

<style>
  input[type="radio"] {
    accent-color: blue;
  }
</style>

<input type="radio" name="accent" id="first" checked />
<label for="first">First</label>
<input type="radio" name="accent" id="second" />
<label for="second">Second</label>

Range selectors

<style>
  input[type="range"] {
    accent-color: green;
  }
</style>

<input type="range" />

Progress bars

<style>
  progress {
    accent-color: purple;
  }
</style>

<progress>

As you can see with just a few lines of CSS you can make your forms and user interfaces match the theme of your site. This approach is perfect for minimalist designs that just need a touch of color to make them stand out.
