Enhancing the Search Bar in Bootstrap 4 Dashboard Template: A Step-by-Step Guide

Recently got my hands on the Bootstrap 4 Dashboard template and decided to enhance it by adding a form to the top search bar. However, I encountered an issue where the search bar shrinks and loses its original design.

If you want to check out the Bootstrap 4 Dashboard template, you can find it here.

I suspect that the problem lies within the html/CSS code, but I'm struggling to find a solution that won't compromise the overall design. I'm not very well-versed in the new CSS features introduced in Bootstrap 4.

I attempted the following code snippet, but as mentioned earlier, the form ends up being centered and shrunk:

<nav class="navbar navbar-dark sticky-top bg-dark flex-md-nowrap p-0">
  <a class="navbar-brand col-sm-4 col-md-2 mr-0" href="#">My Site</a>
    <form action="search.php" method="POST">
      <input class="form-control form-control-dark w-100" type="text" placeholder="Search">
    </form>
  <ul class="navbar-nav px-3">
    <li class="nav-item text-nowrap">
      <a class="nav-link" href="logout.php">Log out</a>
    </li>
  </ul>
</nav>

Answer №1

To adjust the size of the form, simply transfer the class w-100 from the input to the form element.

<form action="search.php" method="POST" class="w-100">
      <input class="form-control form-control-dark" type="text" placeholder="Search">
</form>

This modification will ensure that the form occupies a width of 100%.

Answer №2

By setting the input tag to have a width of 100%, which is a relative value, you need to ensure that the parent form tag also has a width of 100%.

To test this, try using the following code (with inline css for now):

<nav class="navbar navbar-dark sticky-top bg-dark flex-md-nowrap p-0">
  <a class="navbar-brand col-sm-4 col-md-2 mr-0" href="#">My Site</a>
    <form action="search.php" method="POST" style="width: 100%">
      <input class="form-control form-control-dark w-100" type="text" placeholder="Search">
    </form>
  <ul class="navbar-nav px-3">
    <li class="nav-item text-nowrap">
      <a class="nav-link" href="logout.php">Log out</a>
    </li>
  </ul>
</nav>
