How to Align Input Elements and Labels on the Same Line in HTML?

Aligning Input Elements with Labels on the Same Line

In HTML, it is often desirable to place a label and an input element on the same horizontal line. However, determining the ideal width for the input element to fill the remaining space can be challenging.

Issue:

The standard approach, using width: auto;, results in a static width for the input element. Alternatively, width: 100%; moves the input to a new line.

Solution:

To achieve the desired alignment, consider the following CSS techniques:

Option 1: Floating Label and Overflow

HTML:

<code class="html"><label for="test">Label</label>
<span><input name="test" id="test" type="text" /></span></code>

CSS:

<code class="css">label {
    float: left
}
span {
    display: block;
    overflow: hidden;
    padding: 0 4px 0 6px
}
input {
    width: 100%
}</code>

This method utilizes the overflow: hidden property to align the input element with the label by preventing line breaks.

Option 2: Table Display

HTML:

<code class="html"><div class="container">
    <label for="test">Label</label>
    <span><input name="test" id="test" type="text" /></span>
</div></code>

CSS:

<code class="css">.container {
    display: table;
    width: 100%
}
label {
    display: table-cell;
    width: 1px;
    white-space: nowrap
}
span {
    display: table-cell;
    padding: 0 0 0 5px
}
input {
    width: 100%
}</code>

This approach utilizes the display: table property to create a table-like layout, where the label has a fixed width and the input element expands to fill the remaining space.
