The goal I have in mind is to create an input field that will contain text like "100%", "54vh", or "32px".
I am attempting to utilize the number input's up and down arrows, while still allowing the user to edit the text. However, it should only allow additions if it recognizes a %, vh, or px symbol in front of the number.

| 54px | ^ |
| | v |

If you try adding strings to number inputs, they won't register the value correctly. A good workaround is to use a <select> tag for units and then combine the two values using either JavaScript or PHP. Here's an example:
<input type="number" name="value" value="">
<select class="" name="unit">
<option value="">%</option>
<option value="">px</option>
<option value="">vh</option>
</select>Additionally, it's best practice not to allow special characters like % or / in input fields. It's safer to handle inputs this way.
