There is no automatic margin calculation for the input element, however, the margin can still be adjusted using metrics and

I'm encountering an issue with the width of an input element within a table cell. The input element is defined in the following way:

<td><input class="form-control input-small my-input-narrow" type="number"></td>

Unfortunately, the width of the table cell is much wider than the input element itself, causing layout problems.

Upon inspecting the element using Chrome, the computed style tab reveals:

margin-bottom: 0px;
margin-left: 0px;
margin-right: 0px;
margin-top: 0px;

Oddly enough, when examining the metrics and hovering over the Margin attribute, a wide area as margin is displayed despite showing "-" as the width of the margin. The computed style for the td indicates a width of 219px, while the input element is only 33px wide.

If you have any suggestions on how I can better understand this rendering issue, please let me know!

Thank you!

Answer №1

A puzzling situation arose for me when I found padding appearing visually despite all styles being set to 0px. Oddly enough, a "-" was still visible in the metrics area. It turned out that an enclosing element had a fixed width, causing the padding to be necessary to fill the space between the inspected element and that outer element with a fixed width.

If you're using Chrome Developer Tools to inspect an element and you see padding or margin showing up while the metrics area displays "-", chances are this is the reason why.
