用于打印替代文本的CSS属性？ [英] CSS property for printing alternative text?
问题描述
嗨
我有一个标题为gif的标题：
< h1>< img src =" mytitle。 GIF" alt ="这是我的标题">< / h1>
所以这是基于文本的浏览器和搜索引擎友好且可以轻松
用样式表格式化。
现在我有一个单独的media =" print"样式表。由于标题gif确实
在打印时看起来不太好，因此有一个CSS属性
输出alt属性中的文本会非常好。
display：none使图像在没有替换的情况下消失。我可以
复制h1标签并给出两个实例类名，可以在相应的样式表中定义
as display：none，但这会让人感到困惑
各类非CSS浏览器。我会喜欢这样的东西：alttext。
有没有办法做到这一点？
感谢您的每一个提示。
Markus
Hi
I have a title with a title gif:
<h1><img src="mytitle.gif" alt="This is my title"></h1>
So this is text-based browser and search-engine friendly and can be easily
formatted with a style sheet.
Now I have a separate stylesheet for media="print". As the title gif does
not look very good when printed it would be very nice to have a CSS property
that outputs the text in the alt attribute.
display:none makes the image disappear without a replacement. I could
duplicate the h1 tag and give both instances class names that can be defined
as display:none in the appropriate style sheet, but that would confuse
non-CSS browsers of all kinds. I would love something like display:alttext.
Is there a way to do that?
Thanks for every hint.
Markus

img：after {display：block; content：attr（alt）}

不，不是。 < H1>搜索引擎是空的。
No, it isn''t. <h1> is empty for search engines.

凌乱，但确实有效。
< h1 class =" noscreen">这是我的头衔< / h1>
< h1 class =" noprint">< img src =" mytitle.gif" alt ="这是我的标题">< / h1>
而且样式显然是屏幕css中的noscreen {display：none;}和
noprint {display：none;}在print css中。
Messy, but it works.
<h1 class="noscreen">This is my title</h1>
<h1 class="noprint"><img src="mytitle.gif" alt="This is my title"></h1>
And the style is obviously noscreen {display:none;} in the screen css and
noprint {display:none;} in the print css.
