Question

I have a client who wants bigger text in an <input> box. I would prefer to not have to make custom graphic button for this as it’s on a really resource-constrained embedded system.

Answer 1

The input tag can be styled just like any other element in HTML, including padding, borders, text font face/size, etc.

input{
    font: sans-serif italic 20pt bold;
    border: 2px black solid;
}

Or what ever you would like.
