xhtml自封闭锚元素< a />允许? [英] xhtml self-closing anchor element <a /> allowed?
问题描述
如果我做一个锚点元素,不想要的文字,因为我要css-i-fy它有一个漂亮的图像和悬停效果...
我想知道如果它是合法的写< a id =hoverimagehref =google.com/>
validome.org& validator.w3.org说是?
If I make an anchor element and don't want text within it, because I'm gonna to css-i-fy it with a nice image and a hover-effect...
I wonder if it is legal to write <a id="hoverimage" href="google.com" />
validome.org & validator.w3.org say YES ?
BTW:对于这种情况,任何人都知道等价于alt元素?
BTW: anyone knows an equivalent to alt element for this case?
推荐答案
这是在XHTML a>。它是不与HTML兼容,因此可能会在作为文本/ HTML的文档中断开。拥有一个没有内容的链接是不好的做法(背景图片不是内容(这就是为什么没有等同于alt属性))。
It is valid in XHTML. It is not HTML-Compatible so likely to break in a document served as text/html. Having a link with no content is bad practise (background images are not content (which is why there is no equivalent to the alt attribute)).
