Change the content of a single page

When you checked the forums did you come across suggestions to use Firebug or an equivalent browser developer tool?

Andrew,

Yes I have seen those. Didn’t use Firebug, but loaded the page source into my off-line editor and tried several options based on the page structure and the hints I had seen on the forum. No luck.
I then thought that because of theme-specific tags and classes the options might work for other themes but not for Twenty Fourteen.

I will install and try Firebug, but I am not really optimistic that I my findings will be very much different.

When you say you want to change the width of the page, do you just mean this bit outlined in red: https://snag.gy/M9fiS.jpg ?

Yes, that’s what I want(ed).
Downloaded and installed Firebug. It helped me better than I had hoped from previous experiences. I checked the page and found the area I wanted the width to change. It took me a couple of tries to address the right parameter in the right way, but I managed to change it.

Thanks very much for your advice. Learned something again.

Actually this is what I needed to add to the child CSS to change the content width of the specific page:

.page-id-231 .entry-content {
max-width: 800px;
}

Hi,

I’m terrible at this tech stuff. I’ve searched all day (seriously 12 hours) for step-by-step directions for how/where to change the width of a single page in Twenty Fourteen. I see that you’ve addressed it here, but when I tried to follow your directions that worked for you, it didn’t work for me. I’m trying to implement this code on this page: https://chickletsinthekitchen.com/printable-coupons/

I installed Firebug and inserted

.entry-content {
max-width: 800px;
}

after my .page-id-3664 It moved the coupon savings center to the left, but that was all. As soon as I refreshed the page it when back to the middle.

Can you tell me exactly what I need to do to change the width to its maximum and make it stick?

Thanks so much!
