Strange border on IMG tag
提问by Mark
HTML:
HTML：
<html>
<body>
<header>
<img class="logo" />
</header>
</body>
</html>
CSS:
CSS：
* {
margin:0px;
padding:0px;
border:none;
}
img.logo {
width:126px;
height:50px;
background-image:url('images/logo.png');
}
One way or another everytime i try to style an IMG like this a strange border appears. Even if I would place border:0px; or border:none; in the img.logo css the border remains.
每次我尝试像这样设置 IMG 样式时，都会以一种或另一种方式出现奇怪的边框。即使我会放置 border:0px; 或边界：无；在 img.logo css 中，边框仍然存在。

It's the default "special" border that appears when you use an imgelement with an a srcattribute set to something that doesn't exist (or no srcat all).
当您使用img一个src属性设置为不存在（或根本不存在src）的元素时，会出现默认的“特殊”边框。
A common workaround is to set the srcto a blank.giffile:
一种常见的解决方法是将 设置src为blank.gif文件：
<img class="logo" src="blank.gif" />
I have to point out that it (in this case) makes no sense to use an <img>with background-image. Just set the srcattribute and forget about background-image.
我必须指出（在这种情况下）使用<img>with是没有意义的background-image。只需设置src属性并忘记background-image.

You can Simply Use divinstead of imgfor background image , if you are not going to use srcattribute anywhere.
如果您不打算在任何地方使用属性，您可以简单地使用div代替img背景图像src。
<div class="logo"> </div>
otherwise srcis required.
否则src是必需的。

This works for me
这对我有用
img {
text-indent: -999px;
}

Combining @thirtydot's answer to this questionwith @Layke's answer for Smallest data URI image possible for a transparent image, here is an all-in-one solution:
将@thirtydot 对这个问题的回答与@Layke 对透明图像的最小数据 URI 图像的回答相结合，这是一个多合一的解决方案：
<img class="logo"
src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"/>
