Can't customize fixed width

Did you changed the theme settings to "fixed width", also?

Just flush the browser cache with CTRL+F5. Do that after any change in css files

I have exactly the same problem, no one of the suggested solutions works. Any other suggestion ?

Regards,

I am sorry but I am unable to reproduce that.

What happens when you changed the theme settings to "fixed width"? Probably it had fixed width. If you change something in custom-style.css you should have no CSS aggregation and flush the browser cache to see the modifications.

When I change the theme settings to fixed width the result is actually fixed width, to 980px I think.
no matter what value I give to body.layout-fixed .sizer on custom-style.css nothing change on the site (of course I delete the cache and refrech the page with Crl-F5).

Here is my custom-style.css file :

/****************************/
/* CUSTOM STYLE CSS         */
/****************************/

Put your custom css and css overrides in this file.  By restricting

Steps to customize your 0 Point theme:                       
1. Add your custom css to this file                
2. Uncomment different examples and modify data as you wish 
3. Clear cached data at admin/settings/performance 
4. Save this file with a different name to avoid loosing it after a theme update.

Any suggestion ?

Sorry for my superficiality ... indeed it is a bug which will be corrected in the next release. You should change the following lines in custom-style.css file:

/*
body.layout-fluid .sizer {
width: 90%;
}
body.layout-fixed .sizer {
width: 1980px;
}
*/

... to:

/*
body.layout-fluid .sizer0 {
	width: 90%;
}
body.layout-fixed .sizer0 {
	width: 980px;
}
*/

... then do the rest, as usual. I forgot to add a "zero" (0) after each ".sizer".

It worked.

Thank you.

The 0 did it for me...now I can bandage up my head and fix the wall I was hitting it against!!!
