UPDATE (18 March 2015): Since first posting this, the full-bleed background has changed from 725px to 724px.
I have been aware of Behance for quite some time but really never forayed into this portfolio space until recently, when I myself needed some updates and upgrades to my own portfolio (still updating).
As I was perusing all the awesomeness on Behance, I noticed some portfolio pages were full-bleed, edge-to-edge, no white borders. Just design. Loved it. I jumped in wanting to replicate this same look. But what I realized, is that you had to slightly trick the portfolio page a little to achieve this look.
I googled Google and really didn’t find anything that was helpful. Just a bunch of templates on Creative Market which assumed you already knew what to do with said templates.
This is what I figured out and thought I would share for those wanting to know.
There are 2-ways of doing this:
1. Create a single designed image that is
725 724px wide and however long you want the page to be.
2. Upload your single image as a BACKGROUND image. Background images cannot exceed 1MB. Leave the position of the image as is and no need to “check” the Repeat/Tile box.
Once uploaded your new background image will only show the first 550px of your single designed image.
3. Next, upload a transparent PNG file of the same dimensions or a little taller than your designed background image. The transparent image will force the entire background image to show.
Same as Steps 1 & 2.
3. Add a text field on top of the background image and hard return all the way down the page until your background image is revealed.
Here are some basic templates in Illustrator and Sketch 3.
Hope this helps.
