Re: Query Regarding SC 1.4.10 - Reflow

No, it's more than that.

Also, a horizontal scrollbar isn't an automatic fail. Sometimes a website has one but it doesn't move far, or a page isn't completely responsive BUT all the text remains visible within the viewport without scrolling.

Quick check: You can read without scrolling horizontally, and you can see and interact with all the content (nothing is missing).

Longer explanation:
- users can read text without horizontally scrolling. This makes reading slower, more difficult and costs the user more energy. If the text content can be read without scrolling, even if for example there's a very large image/figure or something elsewhere which does need scrolling to view, this is not necessarily a failure (depends on the image. Scaling an image or figure to fit a zoomed or small viewport is not always the best thing to do. For example a chart may enlarge and require users scroll to move the viewport to view all the data. Scaling it down may make it too small and some types of graphics are exempted from the Reflow SC).
- no content is cut off
- no content overlaps in a way that prevents users from reading/understanding/interacting with the content
- no content is hidden which shouldn't be hidden (nothing accidentally hidden. Especially focusable content!)
- when zoomed in or in a mobile viewport, the content order still makes sense (does NOT necessarily have to be the same as visible on the non-zoomed or desktop version, but it needs to make sense. Follow the 1.3.2 guideline)
