Style= "Display" Cannot get the value of a measurement such as offsetheight or clientwidth

If the style= "display:none;height:90px;" is set in the HTML element. The properties are not available for offsetleft, offsetwidth,offsettop,offsetheight, and compatibility with better clientheight,clientheight (client). The property will be larger than offset, as it may contain a border or scrollbar, because the browser will not be able to measure it once display:none is not rendered. But you can get the height:90px in the style, and the other CSS property values you set in the style.
