Is there any way to make the bootstrap color picker box bigger ? I looked through it's css but i couldn't find where is setting the box height and weight.
I am using this color picker : Stefan Petre's Bootstrap Colorpicker
Assuming you're using the HTML5 native color picker, you can customize it with CSS :
input[type="color"].custom {
padding: 0;
border: none;
height: 50px;
width: 50px;
vertical-align: middle;
}<div class="container">
<form role="form">
<div class="form-group">
<label for="cp1">HTML5 native Color Picker :</label><br>
<input type="color" name="cp1" value="#9b59b6">
</div>
<div class="form-group">
<label for="cp2">CSS Customized Color Picker :</label><br>
<input type="color" name="cp2" value="#9b59b6" class="custom">
</div>
</form>
</div>bootstrap-colorpicker.js plugin)As the width is hard-coded in the plugin, you'll need to modify the plugin itself. Here's the full JS code which will allow you to simply set your desired size, without changing the original CSS (just modify CPSize value in the first lines) :
