I'd like to give each piece in my portfolio more space on their pages. Currently im trying do hard return in my edit page or entering commands in text, but they dont stay?
If you're working with page content, you can add extra space using the HTML editor. Example:
<img style="padding-top: 3em;" src="YOUR_URL" />
Or you can do it with the CSS editor if it will be the same for every portfolio page and you can find a common selector to use. Find the outside element for the thing you want to add space above (i.e. an image or a gallery) and add some CSS similar this except replace YOUR_SELECTOR with the selector for whatever you're trying to add space to:
Adjust the 3em value as needed.
If you need help finding what selector to use, reply and link to an example page.
