iOS forces rounded corners and glare on inputs

The version I had working is:

input {    -webkit-appearance: none;}

In some webkit browser versions, you may also be faced with the border-radius still being in place. Reset with the following:

input {    -webkit-border-radius:0;     border-radius:0;}

This can be extended to apply to all webkit styled form components such as input, select, button or textarea.

In reference to the original question, you wouldn't use the value 'none' when clearing any unit based css element.Also be aware that this hides checkboxes in Chrome, so perhaps use something like input[type=text] or input[type=submit], input[type=text] or instead filter out those that don't use rounded corner settings such as input:not([type=checkbox]), input:not([type=radio]).

You can get rid of some more webkits form, input, etc. styling with this:

input, textarea, select {   -webkit-appearance: none;}

For the submit button don't use:

<input type="submit" class="yourstylehere" value="submit" />

Instead use the button tag:

<button type="submit" class="yourstylehere">Submit</button>

This worked for me.
