How to add an icon to a search input in Bootstrap 4?
Bootstrap 4 - Search input with an icon
The question involves integrating an icon into a Bootstrap 4 search input. The issue arises as Bootstrap 4 does not support Glyphicons. Here's a detailed explanation of how to incorporate an icon into the search input using various techniques:
Input Group with Append
This technique uses an input-group with an append or a prepend for the icon. The icon is placed either before or after the input field.
<br><div> <input class="form-control py-2" type="search" value="search"> <span><div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><button>
Input Group with Input Group Text
This technique utilizes an input-group with input-group-text for the icon. The input-group-text provides a placeholder for the icon without a gray background.
<br><div> <input class="form-control py-2 border-right-0 border" type="search" value="search"> <span><div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><div>
Grid System (Row & Column)
This technique uses the grid system (row & column) to create a search input with an icon. No-gutters are used to eliminate spacing between columns, resulting in a seamless layout.
<br><div> <div class="col"></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><input>
<button>
Input Group with Prepend
Similar to the input group with append, this technique utilizes an input group with input-group-prepend. The icon is placed in the prepend, located before the input field.
<br><div> <span class="input-group-prepend"></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><div>
<button>
The choice of technique depends on the desired appearance and functionality. These examples demonstrate several methods for integrating an icon into a search input using Bootstrap 4, providing flexibility in design and implementation.
