Sometimes a page looks great on desktop and falls apart on mobile. Text sits at the wrong size, an image lands in the wrong place, or a two column section stacks in an order that makes no sense. Fighting a single block into behaving on every screen usually loses.
SnapPages lets you hide any block from a specific screen size. Open the block settings, look for visibility toggles, and hide it from desktop or from mobile. That block still exists on the page, it just does not render on the size you excluded.
Use that on purpose. Build one version of a section tuned for desktop and hide it on mobile. Build a second version tuned for mobile and hide it on desktop. Both live on the same page. Members see the one that fits their device.
Preview both views before you publish. SnapPages has a device toggle in the editor. Flip it and confirm each screen size shows only what you want. Doing this once is worth ten rounds of pinching and zooming after launch.
