Why Does My Text Area Have Extra Space Below it?

Extra Space Below Textarea: Causes and Solutions

Problem:

Despite using simple markup, extra vertical space appears beneath elements in various web browsers, ranging from 1 to 4 pixels.

Code Snippet:

<code class="html">
    
        <style>
            body {
                margin: 0;
                padding: 0;
            }
            .main {
                background-color: red;
            }
            textarea {
                background-color: gray;
                resize: none;
                margin: 0;
                border: 0 none;
                padding: 10px;
                height: 50px;
                overflow: hidden;
            }
        </style>
    
    
        <div class="main">
            <textarea></textarea>
        </div>
    
</code>

Cause:

The extra space is caused by the default alignment of elements, which are classified as inline (or inline-block) elements. This gap is reserved for the potential descenders in the text below.

Solution:

To eliminate the extra space, add the following CSS rule to your elements:

<code class="css">textarea {
    vertical-align: top;
}</code>

This aligns the to the top of its container, effectively removing the extra spacing.
