Is it necessary to 'set' a maximum screen size?

Know I can set a 100% table that will allow 'scaling' for different user screen resolutions but what if I don't want to set a 100% table?

What if I just type a title and align it to center .... is it aligned to the center of each user's screen?

Thanks

yes

look at your page in your browser. If the page appears in the center of your screen, then it will be centered on other people screens, too.

If You use css for layout, then you must upload css file on server

It's not necessary at all - make your site the way you want, but always sparea thought for your visitors

Conundrum ... which is right?

I'm trying to set a background image that is a gradient .... starting with candy apple red on left of screen and changes to very dark red - almost black - on right side (with intense yellow text for readability).
I'm using DW 8 but do not have Fireworks or Photo Shop (am using Paint Shop Pro 7) and have created an image that has the background I want ... but how big should it be? ... and repeat , or repeat-y or repeat-y?

Or create a 100% table covering the whole 1st page and use the image as the table bkgnd? (But if do that instead of 'redefine' the body tag, doesn't that defeat one of the strengths of CSS because then I'd have to do that for the other 20 or 30 pages if the website?)

CONUNDRUM

Thanks again for any help.

You're right on your second point. Go for styleing the body tag, it's far cleaner and easier.

Without seeing the image it's difficult to answer your first question... if it's a horizontal gradiant, you can have it repeating on the Y axis. If you set the background colour of the page to be the same as the far right colour in the gradient, it will look more normail on browser windows that are larger than the image.

Thnak you ... the background IS a horizontal gradient.

have used 100% tables (instead of layers) and made columns %ages (using CSS whenever possible - at least at my edu level) ... so seems to be ok for 1024x768 and 899x600 screens. 3 cols per table ... made each 33% so middle one is 'centered. Makes my initial question unnecessary.
