As for the earlier example of a button that takes the user to the very bottom of the page, all this should take place in a minimum of. seconds, so that this action is not captur in CLS. How to ensure good CLS value? Cumulative Layout Shift buildup leads to: so-call flash of invisible text (FOIT) or flash of unstyl text (FOUT). FOIT occurs when the browser nes information about the font from the server. Until it receives it, the target text is not visible, and the user in its place does not see anything. FOUT happens for similar reasons, but in this case the text loads.
Here are some rules to help you avoid
Since the browser also receives information about the font with a delay, the visible text does not have the right style for a while. Placing images without specifying their exact dimensions. Ads in the form of banners without specifying dimensions. Actions that expect a response from the network before updating the DOM (Document Object Model). Any content that is add dynamically. problems with CLS: Always include size attributes on photos and video Wuhan Mobile Phone Number List elements, or otherwise reserve the requir space, e.g. with CSS aspect boxes. This ensures that the browser will always be able to allocate the appropriate amount of space on the page in advance when loading an image.
This solution makes it possible
You can also use the so-call unsiz-mia feature policy to make this scaling behavior the default. Never put content on top of what already exists . The exception is when the user’s action is suppos to lead to such a state of affairs. Thanks to this, any changes taking place in the system will not be unexpect (and therefore undesirable). Use animations that ensure smooth transitions. for the user to constantly see where he is being mov during the transition LOB Directory on the page, thanks to which he maintains a point of reference.
