input type=“image” shows unwanted border in Chrome

问题:

I have not found a solution yet...

I tried everything

border:0;
border:none;
outline:none;

without any luck...and the funny thing is the broken link icon in IE7 which overlaps my image.

Any suggestion? link here

HTML (generated by WordPress)

<form id="searchform" method="get" action="http://eezzyweb.com/">
   <div>
  <input id="s" name="s" type="text" value="" size="32" tabindex="1"/>
  <input id="searchsubmit" name="searchsubmit" type="image" value="" tabindex="2"/>
   </div>
</form>

CSS

input#s{
position:relative;
width:245px;
height:28px;
border:0;
vertical-align:bottom;
background:url(images/input-search-bkg.png) 0 0 no-repeat;
}

#searchsubmit {
display:inline-block;
background:url(images/submit-bkg.png) 0 0 no-repeat;
width:30px;
height:30px;
border:0;
vertical-align:bottom;
}

Firefox and Opera render the image button ok, but in Chrome and Safari I get that grey border around it. IE 7 and 8 add a symbol (broken icon?) over my image... I am baffled.

回答1:

You are using the image as a background. Why not set it as the src property of the button ?

<input src="images/submit-bkg.png" id="searchsubmit" name="searchsubmit" type="image" value="" tabindex="2"/>

When you set the type as image the input expects an src attribute as well..

For reference, if you want to stick to using CSS to give the button an image, for reasons such as providing a :hover or an :active rule, you can keep your code as is and add the button an invisible image, i went with:

<input type='image' src='invisible.png'/>

Which means its a completly transparent image, size doesnt seem to matter, but i went with 1 px by 1px.

This worked for me:

input[type="image"]:focus {
    outline: none;
}

回答4:

Chrome, IE, and Safari parse the code foolishly.

<input type="image" src="bleh.png">
<input type="image" src="bleh.gif">

is not parsed the same by these browsers as

<input type="image" src="bleh.png"><input type="image" src="bleh.gif">

Put all of your image inputs on the same physical line in the coded document. I just about punched a whole through my monitor with the same problem until I realized this.

This is ugly but it works...

<input id="saveForm" style="border:0px;" type="image" name="submit" value="Submit" BORDER="0" src="./images/button_submit.png" />

Try this

a:active {
 outline: none;
}
a:focus {
 -moz-outline-style: none;
}
a, input {
 outline-color: invert;
 outline-style: none;
 outline-width: medium;
}
