I am trying to create a very generic mega menu using pure html/css without using bootstrap (for some reason there is no tutorial online, so I am making one myself). I have managed to style my nav correctly and it works responsively, but I can't figure out how to make the mobile version give me a menu option instead of providing all the links as they currently are. I will post the code below and if I anyone can show me what to add to make it happen that'd be awesome!

<div class="menu style">
            <ul class="menu">
            <!-- Mega Menu start. copy section between comments to create new heading-->
                <li><a href="#">Option 1</a>
                    <div class="mega-menu">
                        <div class="col-1">
                            <h4>Header 1</h4>
                                <ol>
                                    <li><a href="#">Content</a></li>
                                    <li><a href="#">Content</a></li>
                                    <li><a href="#">Content</a></li>
                                    <li><a href="#">Content</a></li>
                                    <li><a href="#">Content</a></li>
                                </ol>
                        </div>
                        <div class="col-1">
                            <h4>Header 2</h4>

Updated your code with a hamburger menu under mobile screen, made the drop down static positioned as it won't overlap on other menus.

Check out this snippet. Run this is both large and small screens. I think this is what you are looking for.

jQuery(function($) {
  $('.menu-btn').click(function() {
    $('.menu.style').toggleClass("open");
  })
})
@font-face {
  font-family: 'raleway';
  src: url(fonts/raleway/raleway.ttf) format('truetype');
  src: url(fonts/raleway/raleway.otf) format('opentype');
  src: url(fonts/raleway/raleway.woff) format('woff');
}

    This was exactly what I was looking for! Thank you so much! Navigation menus have always been a weakness for me when it comes to being responsive. I will use this for the future and I will create a free tutorial on this for others (I will credit you with the assist!) Thanks. On a side note, I would love to figure out how to make the main nav option disappear and place the hamburger button in the top right corner instead. The site I am working on has a huge banner on the home page right above the main nav, so clearing that space on mobile would be great, but I will figure that out myself. – aroveruser Dec 21 '15 at 22:03
  • Effiecient use of media query in your css is the right way to do responsive design. – Jinu Kurian Dec 22 '15 at 02:18
