Please indicate a width of 3 characters for the HTML input text

Is there a way to create an HTML text box that can only fit 3 characters exactly?
I came across this code online:

<input type="text" style="width: 10px; padding: 2px; border: 1px solid black"/>

This code creates a text box with a width of 10px. While this works, I'm curious if there is a method to explicitly set it for 3 characters instead of adjusting pixels.

Answer №1

Employ the ch unit of measurement.

width: 3ch;

Ensure that your box-sizing attribute is configured to content-box when adjusting left and/or right padding.

Answer №2

It's not guaranteed due to the varying widths of characters like l and W.

But, opting for a monospaced font can improve consistency. You could try setting size="3" on the input element while using this font, theoretically resulting in a width of three characters.
