Hi @Peter_1985 ,
The reason for this problem is that you set the visibility property to "hidden".
An element can be hidden by setting the display property to "none" or the visibility property to "hidden".
Note, however, that these two methods will produce different results.
visibility:hidden can hide an element, but the hidden element still needs to occupy the same space as before.
display:none can hide an element, and the hidden element will not take up any space.
