Troubleshoot design and layout issues in Adobe Muse websites. Look for hidden objects and objects outside margins.
Alignment issues are usually the result of objects lying outside the layout. This issue is most commonly seen when you copy contents from a layout with larger dimensions to one that are smaller. For example, when you copy and paste contents from a desktop to a mobile layout, chances are that some objects are placed outside the layout. They are especially invisible if you have disabled Frame Edges.
When you publish a layout with such objects, the browser includes the space containing the objects outside the layout. The extra space makes your page look smaller and incorrectly aligned.
