Let me try and give this a shot.
- The diamond icons correspond to the margins of your page. Because you have an image exceeding the margin on the left, the marks are beyond the page.
- Similarly, to get the contents to fit within the page from the right, drag the slider to make it fit.
About the space in the end, make sure you have enabled sticky footer. Creating Headers and Footers in Adobe Muse
Thank you very much for the reply. Your explanation has been useful. I have a page that is stubborn, I can't set the page length as I did with the other pages. If I may, I would like to send you the Muse (only) page that is causing a problem. If you succeed to repair it, I want to know exactly what you have done so that I can learn. It looks good in Design mode but in a browser, there is a big gap at the end of the page. What would be the best way to share the file with you? Thanks a lot.
I am Preran's colleague and will be happy to look into your issue.
You can send me your affected muse page via Dropbox and share the download link either here or in a private message.
