How remove border around image in css?

I try to display a span when the cursor of the mouse is on a help icon.

It works, but nevertheless, I don't manage to remove the border around the icon.

My CSS :

.info{
    position:absolute;
    border:none;
}

a.info{
    position:absolute; 
    z-index:24; 
    background:none;
    color:#000;
    text-decoration:none
}

a.info:hover{
    z-index:25; 
    background-color:#FFF;
    cursor:help;
}

a.info span{
    display: none
}

a.info:hover span{ 
    display:block; 
    position:absolute;
    cursor:help;
    bottom:0px; 
    left:26px; 
    width:150px;
    padding:4px;
}

cd

Another thing - remember that if you have an with an empty src attribute, then none of these suggestions will work, a border will still get shown.

<img src="" style="width:30px;height:30px;">

Try this:

img{border:0;}

You can also limitate the scope and only remove border on some images by doing so:

.myClass img{border:0;}

More information about the border css property can by found here.

Edit: Changed border from 0px to 0. As explained in comments, px is redundant for a unit of 0.

img need src to use border is remover, i no know a why css is crazy

data:image/gif;base64,R0lGODlhAQABAPcAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAP8ALAAAAAABAAEAAAgEAP8FBAA7

So try example with SRC:

img.logo {
	width: 200px;
    height: 50px;
	background: url(http://cdn.sstatic.net/Sites/stackoverflow/img/sprites.svg) no-repeat top left;
}

<img class="logo" src="data:image/gif;base64,R0lGODlhAQABAPcAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAP8ALAAAAAABAAEAAAgEAP8FBAA7">

So try example without SRC:

img.logo {
	width: 200px;
    height: 50px;
	background: url(http://cdn.sstatic.net/Sites/stackoverflow/img/sprites.svg) no-repeat top left;
}

<img class="logo">

lol... css crazy! good fun

it's a good idea to use a reset CSS. add this at the top of your CSS file

img, a {border:none, outline: none;}

hope this helps

<img id="instapic01" class="samples" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"/>

I faced similar problem with img tag I had added following line with img tag.

<img class="my-class">

And this is the css class

.my-class{
    background-image: url('add.gif');
    background-repeat: no-repeat;
    display: inline-block;
    width: 27px;
    height: 27px;
}

I changed the img tag to span tag with same css class. Border is not visible now.

<span class="my-class"></span>

Use:

div {
  background: url()
}

instead of <img>. There is no borders in the div with background image.

maybe add border:none to under a.info:hover span or text-decoration:none

I realize this is a very old post, but I encountered a similar issue in which my displayed image always had a border around it. I was trying to fill the browser window with a single image. Adding styles like border:none; did not remove the border and neither did margin:0; or padding:0; or any combination of the three.

However, adding position:absolute;top:0;left:0; fixed the problem.

The original post above has position:absolute; but does not have top:0;left:0; and this was adding a default border on my page.

To illustrate the solution, this has a white border (to be precise, it has a top and left offset):

<img src="filename.jpg"
style="width:100%;height:100%;position:absolute;">

This does not have a border:

<img src="filename.jpg"
style="width:100%;height:100%;position:absolute;top:0;left:0;">

Hopefully this helps someone finding this post looking to resolve a similar problem.

img {
  text-indent: -20000px; /*some large value*/
}

did the trick for me (for Chrome). This will remove the alt icon as well, something to note.

What class do you have on the image tag?

Try this

<img src="/images/myimage.jpg" style="border:none;" alt="my image" />

Here's how I got rid of mine:

.main .row .thumbnail {
    display: inline-block;
    border: 0px;
    background-color: transparent;
}

Thank for the answers,

The border is removed for Internet Explorer, but this there for Firefox.

So, I added this class to the img:

.clearBorder{border:none;}

And it worked!

Also, in your html, remember to delete all blanks / line feeds / tabs between the closing tag and the opening tag.

<img src='a.png' /> <img src='b.png' /> will always display a space between the images even if the border attribute is set to 0, whereas <img src='a.png' /><img src='b.png' /> will not.

<img style="border:0;outline:none" width="200" height="200"
    src="this-image-dont-exists.png"
    data-default="data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg=="
    onerror="if(!this.src != this.dataset.default) this.src=this.dataset.default" />
 

if image dont have src or image url is not returning image, border will be there, so you have to set a empty but valid image , here is a example which will load a default image on image loading error

<img style="border:0;outline:none" width="200" height="200"
    src="this-image-dont-exists.png"
    data-default="data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg=="
    onerror="if(!this.src != this.dataset.default) this.src=this.dataset.default" />

 

I do believe you need to add the border: none style to your icon element as well.

I usually use this on the top of css file.

img {
   border: none;
}

Try this

<img width="30" height="30"/>
