Maximum content not maximized

More:
Using the Theme Name: Twenty Fourteen
Page set to “Full Width Page” Template

Ok, edited the style sheet, it fixed it, but it did change it for ALL pages.

.page-content {
margin: 0 auto;
/* Changed on 10/10/14
max-width: 474px;
*/
max-width: 100%;
}

To restrict your css to just that page, include the page id selector:
.page-id-43 .page-content {
margin: 0 auto;
max-width: 474px;
max-width: 100%;
}

Its not advisable to edit the style sheet, since this will be overwritten by a theme update. Use the Simple Custom CSS plugin or similar.

How do I use the Simple Custom CSS? I installed it but where is the “how to” documentation on these plugings?

Where (or how) do you put the changed CSS into Simple Custom CSS?

I entered the CSS into the Appearance>>Custom CSS and now the site is back to the way it was in the beginning… Broken

It seems to have created the css here–> https://sia-corp.com/?sccss=1&ver=4.1 ?

However, it doesn’t seem to matter what I do now, I can’t get this to display bigger.

Not much comes with documentation…

Go to Admin page > Appearance > Custom CSS. Delete what’s there are try this snippet. Sorry, this stuff can be a bit trial and error sometimes.

.page-id-43 .site-content .entry-header,
.page-id-43 .site-content .entry-content
{max-width:782px}

Yeh, I played with it and got it to work finally. Its pretty much what you have. I didn’t realize they changed the theme and changed the CSS tag to entry-content from what it was before. Let me know if its wrong to use post-43…that’s what it looked like to be when I viewed the CSS.

This worked:
.post-43 .entry-content {
margin: 0 auto;
/* Changed on 10/10/14
max-width: 474px;
*/
width: 800px;
max-width: 800px;
}

.post-43 is OK as well. If you miss out the entry header bit the “Online Store” bit won’t line up.

.post-43 .entry-header,
.post-43 .entry-content
{margin: 0 auto; width: 800px; max-width: 800px}
