3 Steps Simple Responsive Hamburger Menu In Pure CSS

Welcome to a tutorial on how to create a simple responsive pure CSS Hamburger Menu. Yep, there are plenty of other hamburger menus on the Internet, but some of them still require the use of Javascript. So here it is, a menu that is purely CSS-driven, not a single line of Javascript. Read on to find out how to build one!

HOW TO BUILD A HAMBURGER MENU

Building a hamburger menu is actually not that difficult these days with the help of modern CSS…

 

STEP 1) THE HTML

index.html
<!-- (A) MENU WRAPPER -->
<nav id="hamnav">
  <!-- (B) THE HAMBURGER -->
  <label for="hamburger">&#9776;</label>
  <input type="checkbox" id="hamburger"/>
 
  <!-- (C) MENU ITEMS -->
  <div id="hamitems">
    <a href="a.html">First</a>
    <a href="b.html">Second</a>
    <a href="c.html">Third</a>
    <a href="d.html">Forth</a>
  </div>
</nav>

The HTML part should be pretty straightforward:

  1. First, we create the wrapper for the navigation menu <nav id="hamnav">.
  2. Followed by using a <label for="hamburger"> and <input type="checkbox" id="hamburger"/> as the hamburger button. For people who are new, that &#9776; is the HTML symbol for the “3 lines hamburger icon”.
  3. Finally, we sandwich the menu items <a> inside the  <div id="hamitems"> wrapper.

That’s all, zero Javascript involved.

 

 

STEP 2) CSS FOR BIG SCREENS

ham-menu.css
/* [ON BIG SCREEN] */
/* (A) WRAPPER */
#hamnav {
  width: 100%;
  background: #000;
}

/* (B) HORIZONTAL MENU ITEMS */
#hamitems { display: flex; }
#hamitems a {
  flex-grow: 1;
  flex-basis: 0;
  padding: 10px;
  color: white;
  text-decoration: none;
  text-align: center;
}
#hamitems a:hover { background: #401408; }

/* (C) HIDE HAMBURGER */
#hamnav label, #hamburger { display: none; }

The CSS is where all the magic happens. This may seem to be a little complicated, but let’s take it step-by-step. Starting with how to display a “normal menu bar” on the big screens:

  1. Self-explanatory, a full-width navigation menu.
  2. Next, we set #hamitems to display: flex. Adding flex-grow: 1 and flex-basis: 0 to the menu items will automatically space them out equally.
  3. Since we do not need the hamburger icon on the big screen, we hide it by attaching display: none to #hamnav label and #hamburger.

This is actually all the important mechanics on the big screen, and we now have a working horizontal navigation bar.

 

 

STEP 3) RESPONSIVE CSS FOR SMALL SCREENS

ham-menu.css
/* [ON SMALL SCREENS] */
@media screen and (max-width: 768px){
  /* (A) BREAK INTO VERTICAL MENU */
  #hamitems a {
    box-sizing: border-box;
    display: block;
    width: 100%;
    border-top: 1px solid #333;
  }
 
  /* (B) SHOW HAMBURGER ICON */
  #hamnav label { 
    display: inline-block; 
    color: white;
    background: #a02620;
    font-style: normal;
    font-size: 1.2em;
    padding: 10px;
  }

  /* (C) TOGGLE SHOW/HIDE MENU */
  #hamitems { display: none; }
  #hamnav input:checked ~ #hamitems { display: block; }
}

Lastly, we add some style changes on the small screen to do the responsive magic:

  1. Transform the horizontal menu into a vertical one by adding #hamitems a { width: 100% }
  2. Show the hamburger icon with #hamnav label { display: inline-block }.
    • Take extra note – We are showing the hamburger label only, the checkbox remains hidden.
    • The checkbox will still work when the user clicks on the label.
  3. A little confusing, but this is where the magic happens.
    • By default, #hamitems { display: none; } will hide the menu items.
    • #hamnav input:checked ~ #hamitems { display: block; } in simple English – Show the menu items when the hidden checkbox is checked.

 

 

USEFUL BITS & LINKS

That’s it for the code, and here is a small extra that you may find useful.

 

STICKY MENU BAR

Want the menu bar to be permanently fixed on top of the screen as the user scrolls down on your website? Simply add a position: sticky to the navigation bar, and that should do the magic.

theme.css
#hamnav {
  position: sticky;
  top: 0;
}

But this will probably cause more problems on a small screen, so use it wisely.

 

BIGGER HAMBURGER?

The hamburger icon is an HTML symbol. Yes, changing the size is as easy as setting label[for="hamburger"] { font-size: XX em }.

 

I WANT DROPDOWN ITEMS!

That won’t be “simple” anymore, but feel free to challenge yourself…

 

COMPATIBILITY CHECKS

This hamburger menu works nice across all modern browsers.

  1. Step 3 has an extra slash here: //* (B) SHOW HAMBURGER ICON */

    This tripped me up for the last hour…

    Note to self, when learning HTML do not copy paste.

    Otherwise great tutorial.

    The codes for pure html and css responsive design were easy to follow and easy to understand.

  3. can you make the hamburger change to a X on click ? i saw this can be done with before after .. but can`t really understand it.

    1. Faster to just add 3 lines of Javascript.

      <label for="hamburger" id="hamlabel">&#9776;</label>
      <input type="checkbox" id="hamburger"/>
      <script>
      document.getElementById("hamburger").onclick = function(){
        document.getElementById("hamlabel").innerHTML = this.checked ? "X" : "&#9776;" ;
      };
      </script>
