Well, the main problem is HTML sucks. It can't do things literally everyone wants to do at one point or another.

One example, scrolling table with fixed table head. Why is that not something I can specify declaratively? Why is that next to impossible, even with the aid of JavaScript.

Where are tabs? Where are image carousels? Why is it that styling forms elements is still essentially impossible? Where are <select> elements with icons? Where are calendar date pickers that allow me to select multiple dates and ranges?

Why was three columns with header and footer declared the "Holy Grail" of CSS for a decade? And does anyone remember building rounded corners with <b> tags?

Basic basic basic structures that literally every developer is asked to build don't exist. Every developer everywhere has wasted ridiculous amounts of time making something barely functional which should have been stupidly simple.

You can:

    tbody {display:block; height:50vh; overflow:scroll;}
