Thanks for answers.
joaonl i am using a freeflarum service so probably i don't have access for that.
Ralkage the version is 0.1.0-beta.7
I planned to share this style when it is completed, so no problem with showing code for header, and i provided a link in my first post, to actually see how it works.
<nav style="height:120px;">
<a href="#" style="display:inline-block; font-size: 60px; text-decoration: none; margin-left:30px; color:white; background-color:#1098a6; margin-top:12px; padding:5px;">FORUM</a>
<div style="float:right; color:white; margin:20px 15px auto;">
<a href="#" style="color:white"><button style= " display:inline-block; height:80px; width:80px; background-color:#1098a6; border:none; outline: none;">Home</button></a>
<a href="#" style="color:white"><button style= " display:inline-block; height:80px; width:80px; background-color:#1098a6; border:none; outline: none; ">Forum</button></a>
<a href="#" style="color:white"><button style= " display:inline-block; height:80px; width:80px; background-color:#1098a6; border:none; outline: none;">FAQ</button></a>
<a href="#" style="color:white"><button style= " display:inline-block; height:80px; width:80px; background-color:#1098a6; border:none; outline: none;">Rules</button></a>
<a href="#" style="color:white"><button style= " display:inline-block; height:80px; width:80px; background-color:#1098a6; border:none; outline: none;">Contact</button></a>
</div>
</nav>
Pretty simple, just using div, nav, a and button with styles of course.
EDIT:
Fixed with adding @media.
