How to expand your Divi standard section to full height with one line of code

by Jan 24, 2018Code Snippets, Web Design

I’m working on a client site this week and I’m going for a modern, almost futuristic design.

It’s important to me the header is eye-catching, so I wanted to make the header area — also known as the Hero area — full height with left aligned elements.

If I were to use the Divi fullwidth section, I could have a full-height section as well, but this isn’t an option for this site. To achieve left aligned elements, I have to use a standard section because the fullwidth section is one column, fullwidth across the screen.

This means I’m stuck using the standard section, but full height is not an option when you’re using the Divi standard section.

So what do you do?

This is one of those times when knowing a bit of code is useful even if you’re just a Divi designer.

The code I’m using here is one simple line of CSS, and here’s what you do.

Step 1: Define the CSS Class.

Open up the settings for your section and go to the “advanced” tab. There, define the CSS Class. I named mine header. Save and exit.

Step 2: Add this code.

Open up Divi Theme Options and down at “Additional CSS” add this line of code.

.header {height: 100vh;}


Step 3: Confirm it worked.

Open the page in a new browser tab and refresh to see the new full-height section.


If you’re curious how this works, you’re defining 100% of the viewport height. This will ensure the section — regardless of device — will be full height.

    Thank you! The only way to make a full height section was using the full width header module but that limits divi’s potential so much! This quick fix worked great!!

    Sorry i didn’t work. I have added the header class on the section and also added the css code you mentioned on the divi editor on the dashboard. It didn’t work. You can check my site for proof

      Did you put it in the CSS editor for that particular section?

    How can you center your content (vertically and horizontally) in that fullscreen section though? Thank you!

    i tried this.. because i also would like so much to use regular section as a fullscreen heigth.
    Tried your idea … but it’s not working on mine- should be becouse i’m using it combined with other full width header on the same page?
    I will apreciate any help!

    thanks, just what I needed

    • Ysmay

      Super! Glad it helped!

    Thank you so much. This is briliant 🙂
    I believe you could also type “100vh” in the ‘Min Height’ property within the ‘Design’ -> ‘Sizing’ settings of your section. That worked for me. Thanks again for the inspiration and short explanation!

    • Ysmay

      Yes! You can also use 100vh in the CSS settings for the section. But then the menu items and headers reappear when scrolling. 🙂

      • Daniel

        In fact I would strongly recommend Max Width 100vw and Min Height 100vh over the CSS styling. Without this when you turn your page horizontal, the section will end once you start scrolling down!

        • Ysmay

          Yes! Good point, thinking of mobile. 🙂

    This is so amazing – saved me a lot of time (and hair haha) Thanks so much.

    • Ysmay

      LOL! You’re welcome. 😀

    I have tried the exact same thing to achieve a similar effect but my problem is with mobile browsers. Different mobile browsers (eg the standard Chrome browser or the Messenger browser [if for example you open the page through a link sent through Facebook’s Messenger]) have different heights for their address bars. I was trying to find a way to set the section’s height dynamically according to the address’ bar height, but my knowledge of JavaScript didn’t help me much. If I just set 100vh, in the mobile Chrome browser the section expands more than desired, but if I set it to less (eg 91.5vh) it displays as desired in Chrome but not through Messenger. Do you know any way to fix this?

    • Ysmay

      There’s not a lot we can do about Facebook Messenger’s browser, unfortunately. Facebook is notoriously buggy with their Messenger Browser.

      However, what you can do is set different VHs in the CSS for phone. You can set it to something like 90vh or 80vh. You can get to this screen by mousing over the title of the CSS, and clicking the phone icon. Mobile CSS
