what is the difference between "visibility:collapse" and "display:none"
visibility:collapse
should only be used on tables. On other elements it will act as a visibility:hidden
.
visibility:hidden
hide the element but still take the space of the element whereas display:none
won't even keep the space.

Short version:
The former is used to completely hide table elements. The latter is used to completely hide everything else.
Long version:
visibility: collapse
hides an element entirely (so that it doesn't occupy any space in the layout), but only when the element is a table element.
If used on elements other than table elements, visibility: collapse
will act like visibility: hidden
. This makes an element invisible, but it will still occupy space in the layout.
display: none
hides an element entirely, so it doesn't occupy any space in the layout, but it shouldn't be used on table elements.
visibility:collapse
has a display:none
behavior only for table elements. On other elements, it should render as hidden
.
