On my website, it's important that some pages have a different size than others, since some will have more text and need more vertical space.

The problem is, I've just noticed that the website dimensions are global (from the Page Properties window). It doesn't seem to be possible to change the dimensions for specific pages, since they're grayed out unless the front page is selected. Is there any way around this? Thanks!

Oops, it seems that the dimensions were grayed out because I had something else selected, and not because it wasn't the front page... Sorry about that, please ignore this thread!

The website dimensions are not global - you can have varying properties for each page.

Open your site in VSD. Click "Show page" and choose the page whose dimensions you want to edit. Once there, hit the "Page" icon at the top. It will bring up a box, which has a section called "website dimensions". You can change the height of your page in this box - it will change the height for that page only, not the entire site.

Hope that helps!

ETA: glad you figured out the problem!

Under settings at the top of VSD you can set standard settings for new pages, but you can also apply these changes to every page in your site. Becareful.
