As html5 (represented by h5 later) labels become more and more widely used, it is annoying that IE does not recognize h5 labels.

In Firefox, chrome, and other browsers, if you encounter unknown labels, you only need to give a display: block attribute to make this element a div-like element, however, it is disgusting to be on IE. If you do not know it, you do not know it. If you add anything in html or css, it ignores you.

Nothing can be solved by the omnipotent programmer. In fact, it is necessary for IE to identify a custom tag (IE considers h5 tags as unfamiliar and illegal)
