隐藏没有选择器的网站的一个div部分

Question

I am trying to hide a single snippet of code on my website as I upgraded to beta software and can't revert back without playing with my database.

I have attempted to use JQuery which I have achieved before though this div has no selector.

I am a graphic designer though have a small knowledge of code.

I also don't know how to find where the snippet has been input either nor can I just change the CSS. You can see it as the beta license warning in the yellow box.

Any help will be appreciated, the website is (Removed to prevent abuse)

Answer 1

Assuming this use case is actually legitimate and you have a valid license, you could just select child elements, for example to remove the beta warning:

$('#main-body div div div:first-child').css('display', 'none')

This selects the first child within several nested div elements, and hides it using the style display:none;

Answer 2

document.getElementById('main-body').children[0].children[0].children[0].style.display = 'none';

When the above code is called the div will be hidden.

It basically gets the position of an element with a selector, and then goes from child to child and then finally hides the snippet of code.

Hope this helps.
