Web Site Width

[Coldicote]

I have a modest website, mostly created 2 or more years ago. It used to appear normal on my screen, but for some reason it now fills only about 2/3rds of the width of the screen and I am concerned that others probably find likewise. I can correct it by adjusting the zoom level but think that shouldn't be necessary. Can anyone suggest why this is happening please or what I might do about it?
For example: www.skeef.freeserve.co.uk/oldtimes

First things first, you should fix the hundreds of errors: http://validator.w3.o...foldtimes%2findex.htm
http://jigsaw.w3.org/...foldtimes%2findex.htm

Then you need to set the DOCTYPE properly for XHTML 1.0 Transitional, and fix any errors this creates.

Finally, you need to test the site on something other than Microsoft Internet Explorer. E.g. the sound doesn't play at all on Google Chrome, unsurprisingly...

Hello Mark, Thank you, I must say I envy you your knowledge and I obviously have a lot of work to do.
