How to avoid CSS ch layout shifts
Blog post from LogRocket
CSS layout shifts, which occur when webpage elements unexpectedly move during rendering, can result in a poor user experience by disrupting interaction and accessibility. This phenomenon is often influenced by dynamic content changes, asynchronous loading of resources, CSS animations, and font loading issues. The CSS ch unit, which represents the width of the "0" character in a font, is commonly used for responsive designs but can lead to layout shifts due to its reliance on font attributes. To address these shifts, developers can employ strategies such as using fixed-width containers, limiting dynamic content, implementing padding or margins, and replacing ch units with more consistent alternatives like rem units. Additionally, employing responsive design principles, utilizing CSS flexbox or grid systems, and testing layouts across various scenarios can help maintain a stable and consistent user experience. The article emphasizes the importance of choosing appropriate CSS units and testing designs to ensure predictable and accessible web layouts.
