How can I force WebKit to redraw/repaint to propagate style changes?

Question

I have some trivial JavaScript to effect a style change:

sel = document.getElementById(\'my_id\');
sel.className = sel.className.replace(/item-[1-9]-selected         


        

Answer 1

This will force repaint while avoid flickering, existing element tinkering and any layout issue...

function forceRepaint() {
    requestAnimationFrame(()=>{
      const e=document.createElement('DIV');
      e.style='position:fixed;top:0;left:0;bottom:0;right:0;background:#80808001;\
               pointer-events:none;z-index:9999999';
      document.body.appendChild(e);
      requestAnimationFrame(()=>e.remove());  
    });
}
