Display:none and Visibility:hidden are all features that hide an element on a webpage, but they are different, and after experimenting, I find that using the Visibility:hidden property makes the object invisible. However, the object's space in the Web page does not change (invisible but can be found), which is equal to leaving a blank area, and the Display:none property will make the object completely disappear (can't see or touch).
"Such an explanation.
But I didn't think it was enough, so I thought about one of his loading problems.
There is a property display:none, is the structure loaded at the same time when the page is loaded? Or is it when he becomes a display:block, when it is loaded?
have attribute Visibility:hidden; structure when loading a page, will it load at the same time? Or when he becomes a visibility:visible; When it is loaded?
The personal view is that:
Display: When his value becomes a block, its structure will be loaded in.
and visibility will load the page at the same time it has loaded it in, because his value is hidden, it occupies the space.
