I struggle to make my header be 85% of the screen height and the following red bar being the rest 15%, please tell my what did I do wrong and how can I make this happen:)

Thank you for the responses, could you guys tell me why when I reduce the height the content of header overlaps with the red bar and how can i solve that?

Here is the code: https://jsfiddle.net/v0bk9u3v/

<header>
        <a href="#"><img src="#" class="logo"></a>
        <ul class="navbar">
            <li><a href="#">Lorem</a></li>
            <li><a href="#">Lorem</a></li>
            <li><a href="#">Lorem</a></li>
            <li><a href="#">Lorem</a></li>
        </ul>
        <div class="headline">
            <h1>Lorem</h1>
            <div class="desc">
                Lorem ipsum dolor sit amet, et denique molestiae sit. Alia mediocrem ei mei, recusabo repudiandae mel et.
            </div>
        </div>
        <a href="#" class="button b1">Lorem ipsum</a>
    </header>

<div class="lorem">
    <h2>Lorem ipsum</h2>
        <p>Lorem ipsum dolor sit amet, et denique molestiae sit. </p>
<a class="button" href="#">Lorem ipsum</a>
    </div>

Add below code in css and this work for desktop you can use media queries for responsive.

body, html {
  height:100%;
}
header {
  height:calc(100% - 130px);
}

  • Thanks, coul you explain to me how does this work? I am talking about this code: body, html { height:100%; } header { height:calc(100% - 130px); } – Feast May 10 '17 at 11:56
  • header { height:calc(100% - 130px); } is reduce 130px in height of 100% which is the red part height. – LKG May 10 '17 at 12:22

Use vh for height of header and the red area. 100vh means 100% of the vertical height of the device.. So assign 85 vh (85%) to header and 15vh (15%) to red area only for desktop version like the below code:

@media(min-width: 768px){
header{height:85vh}
.lorem{height:15vh;}
}

  • Thanks:) I have another question regarding my code: could you tell me why when I reduce the height the content of header overlaps with the red bar and how can i solve that? How could I make the content the header to resize accordingly because now when you reduce height resizing the window it overlaps. – Feast May 10 '17 at 11:28
  • the overlapping is beacause of the font sizes of the h1 in the header , the 2em padding given to it.... just reduce it – Sahil Dhir May 10 '17 at 11:30

See if this helps you: https://jsfiddle.net/v0bk9u3v/

For the first block you were setting the height on the h1, I changed this and set it on the header selector @ line 7

header{
  height:85vh;
}

I also explicity set the height for the lorem block @ line 123 

.lorem{
    height:15vh;
}

Finally to remove this stlying on mobile I added the following at lines 212 - 219 

@media only screen and (max-width: 750px){

header{
  height:inherit;
}  

.lorem{       
  height:inherit;
    }  
  ....  
}

I noticed that at some viewport heights elemlents in your header are too high to fit in the 85% you are setting, so you may have to fine tune that.

Hope this helps
