What is the known bug in browsers related to using 100vw in Webflow?

Published on

One known bug in browsers related to using 100vw in Webflow is the scroll-bar issue. When using 100vw (viewport width) to create a full-width element, some browsers may add a horizontal scroll bar due to a discrepancy in how they calculate the width of the viewport. This can cause an unwanted horizontal scroll bar to appear, creating an unpleasant user experience.

To address this bug, you can use a few workarounds:

  1. Use a negative margin: By setting a negative margin equal to the width of the scroll bar on the affected element, you can counteract the scroll bar issue. For example, if the scroll bar width is 16px, you can add margin-right: -16px; to the element.

  2. Use calc() function: Another solution is to use the calc() function to subtract the scroll bar width from the 100vw calculation. For example, you can set the width of the element to calc(100vw - 16px); to account for the scroll bar.

  3. Use overflow properties: Adding overflow-x: hidden; to the parent container can prevent the scroll bar from appearing in some cases. However, this may also hide any content that extends beyond the viewport width, so it's important to test thoroughly.

It's worth noting that this bug is browser-specific and may not affect all users or all browser versions. Testing your website across different browsers and versions is recommended to ensure a consistent user experience.
