Reply To: Getting flexboxes to fill verticle space

[Paulie_D]

That’s because that .mainContent div wasn’t using flexbox…

It wasn’t set to display:flex and then it need to be a column

.mainContent {
    flex: 1 75%;
    background: black;
    order: 1;
    position: relative;
    display: flex;
    flex-direction: column;
}

Sorted!
