How to adjust the width of OJS to normal width (960px)?

Dear Friends,

I would like to adjust the width of OJS to normal width (960px), both the header and the content below. How can I do it ? thanks.

I can change the header to 960px, by change CSS’s container to 960x. But I can’t change the content below’s width.

What version of OJS are you using? 2.x or 3.x?

I am using 2.4.8.1, thanks.

Are you wanting to force the maximum width to 960px? OJS 2.4.x’s default theme has a flexible width with a minimum of 730px:

#container {
    width: 100% !important;
    min-width: 730px !important;
}

To override this, you’ll need a higher-precedent !important directive.
