Extra Space Below Textarea: Uncovering the Browsers' Disparity

The presence of extra space beneath a textarea element can be a vexing issue, varying in size from browser to browser. Despite the simplicity of the markup, this discrepancy persists.

To elucidate the cause and provide a solution, let's delve into the underlying code:

<code class="html"><html>
    <head>
        <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>
    </head>
    <body>
        <div class="main">
            <textarea></textarea>
        </div>
    </body>
</html></code>

Copy after login

As illustrated in the screenshot provided, browsers display this extra space beneath the textarea differently. To resolve this inconsistency, the solution lies in adding the following CSS property:

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

Copy after login

The rationale behind this disparity relates to the nature of textarea as an inline or inline-block element. Browsers reserve space beneath it to accommodate descenders, which are characters that extend below the baseline. Unfortunately, the exact reason for the varying gap sizes across browsers remains elusive.
