IOS 强制在输入端设置圆角和眩光

have a look to normalize.css

There's a demo where you can test the form elements and see how they look like in ios. There are multiple webkit oriented properties.

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]).

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.

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

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

This is the what I use in my projects

* {
-webkit-tap-highlight-color: transparent;
}
a, article, div, h1, h2, h3, h4, h5, h6, img, section, span {
-moz-user-select: none;
-webkit-user-select: none;
}
input, select, textarea {
-webkit-appearance: none;
-webkit-border-radius:0;
border-radius: 0;
}

You also get this problem in some browsers if you have the following:

<a class="btn btn-primary" href="#" type="button">Link</a>

instead of:

<a class="btn btn-primary" href="#" role="button">Link</a>

This can happen if you change your input element for an anker element and forget to change type to role.

I had this problem on both Chrome and Safari on my IPad.
