100% Height Off-Canvas Foundation 5

Question

I'm using Foundation and have a series of sections at height: 100%.

I'm using the off-canvas menu but it's only matching the height of the first section / the viewport. So once I scroll, the off-canvas menu is no longer aligned to the height of the viewport.

It's a similar issue to Foundation 5 off-canvas full height of device.

I'm ending up with this:

All good

After scrolling down to next section

I think it can be solved by to adding position: fixed to left-off-canvas-menu, but that's not working.

It's driving me mad.

Answer 1

The best option I can find so far is to add a couple of lines of css:

        .off-canvas-wrap, .inner-wrap {
            min-height: 100%;
        }

        .off-canvas-wrap{  
        height: 100%;
        overflow-y: auto;
        }

Although this fixes it for the most part, scrolling on a touch device is not 100% perfect, every now and then you do get a weird scenario where the bottom of the browser drags upwards.

Answer 2

Here's the better answer: it gives both 100% height and allows the center content to scroll.

.off-canvas-wrap, .inner-wrap, .main-section { height:100%; }
.main-section { overflow-y: auto; }
