Currently, text inputs are set to 97% (or 60% for @media(min-width: 450px)). Because of the CSS box model, they are wider than radio groups or checkboxes because they have padding and border.

In my current project, I fixed it by using box-sizing:

input.ui-input-text, textarea.ui-input-text {
  box-sizing: border-box;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  width: 100%;

I couldn't find any disadvantages, I tested it on Chrome and webkit based mobile browsers, and according to, this works on all major browsers.

Is there a specific reason you are using the 97% solution, or can I submit a pull request which fixes this?


Using box-sizing is ideal, but is there a way to target styles where it's not supported because this is a newer feature? I'm guessing WP7, Opera Mini/Mobile, Firefox Mobile, Bada, etc. may not support this so we'd need a crisp way to target this selectively and fall back to the current approach.

Modernizr is able to test for this via


Shouldn't be a problem to extract the needed functions from Modernizr, I'll have a look at it and submit a pull request!


@ugomobi is working on this here #4098. Closing this a duplicate.
