You're right. Setting flex-grow
does not prevent additional elements from being placed within the same flex container, like adding a sidebar. Here's how it works:
Proportional Expansion (flex-grow):
flex-grow
property controls how much space an element will take relative to other elements in the same flex container..main
with flex: 3
will occupy three times more space than any sibling elements with flex: 1
.Adding More Elements (e.g., Sidebar):
.aside-1
and .aside-2
), they will still fit within the same flex container.flex-grow
value.Proportional Allocation:
flex-grow
value..main
has flex: 3
and each sidebar has flex: 1
, .main
will grow to take three times the space of each sidebar.Overall Layout:
flex-wrap: wrap
behavior will kick in, and the remaining items will wrap to the next line.flex-grow
allows flexible space allocation while leaving room for extra elements.Let me know if this helps clarify your understanding!
Another example
.wrapper {
display: flex;
flex-flow: row wrap;
font-weight: bold;
text-align: center;
}
.wrapper > * {
padding: 10px;
flex: 1 100%;
}
@media all and (min-width: 800px) {
.main { flex: 3 0px; } /*flex-grow: 3 (grow to fill extra space) flex-shrink:0 (can shrink if needed), flex-basis: 0px)*/
.aside-1 { flex: 3 0px; }
.aside-2 { flex: 3 0px; }
.aside-1 { order: 1; } /*flex-shrink: 1 allows them to shrink. see above*/
.main { order: 2; }
.aside-2 { order: 3; }
.footer { order: 4; }
}

Yes, your understanding is correct!
Main Element (
flex: 3 0px
):flex: 3
, the.main
element is designed to occupy three times as much space as any item withflex-grow: 1
..main
would still expand to fill the entire row because of theflex-grow: 3
property.Flex-Wrap Behavior:
flex-flow: row wrap
ensures that the flex items (like.footer
) will wrap to a new line if there's no space left on the current line..main
,.aside-1
, and.aside-2
occupy the entire width of the first row, the.footer
element has to move to the next line due to the wrapping behavior.Overall, the combined layout behavior ensures that each item is arranged proportionally and wraps if there isn't enough space.
