How would I create an HTML
text box that exactly 3 characters can fit into it?
I found this online:
Use the ch
metric.
width: 3ch;
Make sure your box-sizing
property is set to content-box
if you're changing left and/or right padding.
Not reliably, since l and W have very different widths.
However, if you set the font to monospace
, that helps. Then, you should be able to set size="3"
on the input element, and in theory it should be exactly three characters wide.
