Add Markup</h1> <p> Add markup to your html file. You can use any number of menu links and any labels or text for your menu links. The markup structure proposed below is desirable to avoid any bugs. You can use any valid class or id name for your <code>nav</code> element. This will be automatically handled by the plugin. <br> <span class="bold" style="color: red;">Note:</span> If you use several menus on one page, don't forget to create unique ids and names for your hidden checkbox elements that have class ".menu-open". </p> <pre class="prettyprint linenums html-lang"> <nav id="gooey"> <input type="checkbox" class="menu-open" name="menu-open" id="menu-open"/> <label class="open-button" for="menu-open"> <span class="burger burger-1"> </span> <span class="burger burger-2"> </span> <span class="burger burger-3"> </span> </label> <a href="#" class="gooey-menu-item"> <i class="fa fa-cab"> </i> </a> <a href="#" class="gooey-menu-item"> <i class="fa fa-automobile"> </i> </a> <a href="#" class="gooey-menu-item"> <i class="fa fa-truck"> </i> </a> <a href="#" class="gooey-menu-item"> <i class="fa fa-rocket"> </i> </a> </nav> </pre> <h1 class="section-label"> 3. Hook up your menu</h1> <p> To indicate your settings, put the following code within a <code>script</code> tag in your <code>head</code> section, html <code>body</code> element or in a separate Javascript file. Here is an example of how to set a horizontal Gooey Menu with pink menu items. Please, remember that a selector's id or class on which <code>gooeyMenu</code> function is called should be identical to <code>nav</code> element id or class in your html markup (in this example, <code>nav</code> id is <code>gooey</code>) </p> <pre class="prettyprint linenums"> $(function() { $("#gooey").gooeymenu({ style: "horizontal", bgColor: "pink" }); }); </pre> <h1 class="section-label"> 4.

You may set menu items indentation by changing left/top/right/bottom or margin properties of menu items and menu open button.
