I have layout like this:
sometimes my layout might look like this (without menu):
sometimes like this (without sidebar):
and finally my layout might transform into this (without menu and sidebar):
I use CSS Grid layout, and when a block is missing, empty areas appear. How to remove this empty areas?
You can consider grid-column/grid-row to place your elements instead of areas like below:
div, aside, main {
border: 1px solid black;
}
.layout {
display: grid;
grid-template-rows: 75px auto 1fr;
grid-template-columns: 260px 1fr;
}
.header {
display: contents;
}
.menu {
grid-column:1/-1;
grid-row:2;
min-height:75px;
}
.sidebar {
grid-column:1 / -2;
}
.main{
grid-column:1 / -1;
}
/*when there is a sidebar "main" will take only the last column*/
.sidebar ~ .main{
grid-column:2 / -1;
}<div class="layout">
