问题描述
我想知道是否最好将alt标签留空（alt =""）
或指定类似alt =''spacer''" ;当提到
只是帮助页面布局的对象时？
-Fleemo
I''m wondering whether it''s better to leave an alt tag blank (alt=" ")
or specify something like "alt=''spacer''" when referring to objects that
merely help the layout of the page?
-Fleemo
推荐答案
不确定它是否对辅助功能有帮助，但是我尝试命名每个alt标签，即使它只是说边界，也可以命名为b $ b。或者spacer。

Not sure if it helps for accessibility, but I try to name every alt tag,
even if it just says "border" or "spacer."

使用说话浏览器并收听您的页面。 alt =" spacer"
内容吗？

Use a speaking browser and listen to your page. Does alt="spacer"
improve your experience? Does it help you to comprehend and use the
content of the page?

首先，它是属性，而不是标签。
其次，不要在不考虑它意味着什么的情况下使用它，以及它可能会给你带来多少帮助。关于这个特定的
问题，没有任何指示。如果你需要问它，你将得到大多数其他alt属性
也是错误的，除非你理解alt属性的_idea_。
这意味着图像的文本替代，当图像未呈现时，实际呈现给用户
。现在想象自己
坐在一个完全黑暗的房间里听一个语音合成器
为你读一页，比如说

或者这个怎么样（不，我不是这样做的）：

什么可以证明使用alt =" spacer"？人们怎么会得到这样的想法？
好吧，如果你使用的是没有
$ b $的alt属性，它会变得更糟b最轻微的想法或线索：

Yucca，
关于网页创作的网页：
First, it''s an attribute, not a tag.
Second, don''t use it without thinking what it means and what it might
help. There''s no pointing in giving an advice about this specific
issue. If you need to ask it, you will get most other alt attributes
wrong too, unless you understand the _idea_ of an alt attribute.
It means a textual alternative to the image, to be actually presented
to the user when the image is not presented. Now imagine yourself
sitting in a completely dark room and listening to a speech synthesizer
that reads a page for you, saying for instance

What could possibly justify using alt="spacer"? How did people ever get
such an idea?
Well, it _can_ get even worse if you are using alt attributes without
the slightest idea or clue:

(Sorry for long quotations, but they are part of the point. People
really have to listen to [or read] such nonsense, over and over again,
especially since it''s often in a navigation area repeated at the start
of each and every page of a site. And the site may proudly present an
accessibility stamp. Bobby approved, or whatever.)
