The causes and solutions for jitter problems caused by Html page height (CSS solution)

Today a customer asked me about the phenomenon of jittering when the page is switched to the navigation. I carefully judged that the problem is that the page height causes the page to jitter. In fact, the fundamental reason is whether the scroll bar is displayed! When the scroll bar is displayed, the entire page will shake! Here is the solution to add code to CSS!

Find the main CSS and add the following code to the header!

html,body{ overflow-y:scroll;}

html,body{ overflow:scroll; min-height:101%;}

html{ overflow:-moz-scrollbars-vertical;}
