Make content narrower

Hey there,

Are you talking about the main content area in your site?

If so you have some CSS currently:

.entry-header,
.entry-content,
.entry-summary,
.entry-meta {
	margin: 0 auto;
	max-width: 958px;
	width: 100%;
}

You could change the max width for the content area like:

.entry-content {
	max-width: 958px;
}

Or are you talking about the grey slider area?

If that’s the case then it appears there is no ID or class so something like:

.site-main > div:first-of-type{
	max-width: 958px;
	margin:auto
}

You’d have to adapt the sizes as required. You may also like to make special considerations for mobile devices.

There is a chance that the theme has a CSS field in the options, if not then you can make a child theme:

Or you can instead use a plugin if you like:

Have a fantastic day! 🙂

Hope this helps.
Take care.
