So with that note I Welcome you all to Codewithrandom with a new blog. I hope you got an idea for the project. Let’s create it using HTML5 & CSS3.

HTML Code in Dropdown

<ul class="hList">
  <li>
    <a href="#click" class="menu">
      <h2 class="menu-title">animals</h2>
      <ul class="menu-dropdown">
        <li>cat</li>
        <li>dog</li>
        <li>horse</li>
        <li>cow</li>
        <li>pig</li>
      </ul>
    </a>
  </li>
  <li>
    <a href="#click" class="menu">
      <h2 class="menu-title menu-title_2nd">names</h2>
      <ul class="menu-dropdown">
        <li>Kevin</li>
        <li>Jim</li>
        <li>Andy</li>
      </ul>
    </a>
  </li>
  <li>
    <a href="#click" class="menu">
      <h2 class="menu-title menu-title_3rd">things</h2>
      <ul class="menu-dropdown">
        <li>bench</li>
        <li>pizza</li>
        <li>Honda CB125</li>
        <li>space</li>
        <li>black matter</li>
        <li>apple</li>
        <li>philodendron</li>
        <li>liver</li>
        <li>brass</li>
      </ul>
    </a>
  </li>
  <li>
    <a href="#click" class="menu">
      <h2 class="menu-title menu-title_4th">Movies</h2>
      <ul class="menu-dropdown">
        <li>Godzilla</li>
        <li>Man on Wire</li>
        <li>Spirited Away</li>
        <li>Interstellar</li>
      </ul>
    </a>
  </li>
</ul>  

In this HTML code we have defined the structure using HTML tags such as <li> List, <a> anchor & <h1>. Now we have basically just given the names and set them in a sequence to give a look of dropdown we have to style them. So for that we have script the CSS code.

In the CSS code we have styled the structure which is defined in the HTML code. We have coded text-decoration and background color using hex code for each and every name which is present in the list so that when the menu expands their background is identical. Let us see the final output.
