Thank you. Could you tell me where this code should be placed? I added it to the Appearance/Edit CSS but nothing changed. Should this be placed in the portfolio-page.php? and if so where?
Thanks Tom – that wasn’t exactly what I was looking for but helpful.
I was referring to the page width once you clicked on a homepage icon. I found this that did the job.
.single-jetpack-portfolio .entry-content {
width: 1000px;
}
