I saw information on the Internet that HTML5 can be dragged. But no matter what I do, it doesn't work. Expert advice

function asd()
{
document.ondragover = function(e){

What browser did you test on?
html5 needs to run in standard browsers such as firefox and chrome.
For reference, it’s very detailed.

There is a slight dragging effect, but it cannot be moved. There is something wrong with the original poster's javascript, please pay attention to the quotation marks.
