Vertical Range Sliders: A Guide for Optimal Browser Support

In the realm of web development, the HTML5 range slider offers a convenient way to control user input within a specific range. However, aligning these sliders vertically can pose challenges across different browsers.

Can't We Just Increase the Height?

Initially, it was believed that simply setting the height of the slider greater than its width would trigger an automatic vertical orientation. However, this approach has limitations:

• Outdated Information: In most browsers, increasing the height no longer influences the orientation.

The Vertical Transformation

To achieve a vertically aligned range slider, consider these browser-specific solutions:

• Modern Browsers (Chrome, Firefox):

  • Apply writing-mode: vertical-lr to establish vertical writing direction.
  • Use direction: rtl (right-to-left) for sliding up to decrease value and sliding down to increase value.

• Legacy Chrome Browsers:

  • Employ appearance: slider-vertical to force a vertical orientation.
  • Set an explicit width (e.g., 16px) to match the default width of vertical sliders in modern browsers.

• Legacy Firefox Browsers:

  • Add an orient="vertical" attribute to the element.

Example Implementation

Incorporate the following code snippet to display a vertically aligned range slider that supports most browsers:

<code class="css">input[type=range][orient=vertical] {
    writing-mode: vertical-lr;
    direction: rtl;
    appearance: slider-vertical;
    width: 16px;
    vertical-align: bottom;
}</code>

<code class="html"><input type="range" orient="vertical"></code>

Conclusion

By utilizing these browser-specific solutions, you can effectively orient range sliders vertically, ensuring consistent and user-friendly input controls across various platforms.
