How to make form responsive

Next, I would like all input fields (textbox and textarea) to have the same width, but they also have to be responsive so small fields on phone, middle size on tablet and large width on desktop. Is this possible? If so how to implement this?
I already search the forum and saw that people set up a fixed width, but that width is whether too small or too large on small or big screen sizes. Can this be done another way?

It depends on the type of fields that you have, but for the most common text-box and text-area fields you can use this code:

.form-textbox {

    width: 300px !important;

}

 

.form-textarea {

       width: 300px !important;

}

 

@media screen and (max-width:600px)

{

.form-textbox {

    width: 90% !important;

}

 

.form-textarea {

       width: 90% !important;

}

}

The blue code is for responsiveness. You can adjust the values.

As I mentioned some additional code might be needed for specific fields.
