Show the iframe upon load, not ealier

[niutech]

When I click on any method, the modal with the iframe appears, but as the docs page is being loaded, first the top of the page is visible, then it jumps to an appropriate anchor after a second, which is annoying.
Instead, please show the iframe upon load, so the page is already positioned correctly. You can do it by setting #iframe { visibility: hidden; } and $('#iframe').addEventListener('load', function () { this.style.visibility= 'visible'; });
