To create a gradient (say blue to pink) as background for my web pages, I can set the default existing background to blue and apply a gradient to that. And that's fine, except the gradient is not consistent on all the pages because the page lengths affect the look of the gradient on each of them.

So, for consistency, is it better to create a new background, colour it blue, apply gradient and set it for each page?
What is the standard practice for this (and I believe Pro X17 has enhanced how this is done?)?

Finally, should the Pasteboard be also given the same gradient?

I'm also wondering how browsers respond to gradients like these?

Thanks in advance,
