我正在为我的所有图像添加 alt
属性以提高 SEO/屏幕阅读器性能.
I'm adding alt
attributes to all my images to improve SEO/screen reader performance.
根据最佳实践,纯美学图像应该有一个空的 alt 属性 alt=""
,以便屏幕阅读器跳过它们.我在 WordPress 中发现它确实将 alt
添加到这些无描述的美学图像中,但没有添加 alt=""
.
Per best practice, images that are purely aesthetic should have an empty alt attribute alt=""
so screen readers skip over them. I'm in WordPress and noticed it does add alt
to these descriptionless aesthetic images, but not alt=""
.
屏幕阅读器和搜索引擎爬虫读取 alt
是否与 alt=""
相同,或者我应该进入并以编程方式强制 alt=""
?
Does alt
get read the same as alt=""
by screen readers and search engine crawlers, or should I go in and programatically force an alt=""
?
是的,都一样:https://www.w3.org/TR/html5/syntax.html#attributes-0
空属性语法
只是属性名称.该值隐含为空字符串.
Just the attribute name. The value is implicitly the empty string.
对我来说,这就是说没有值的属性与具有空字符串的值相同.
To me, that says that an attribute with no value is the same as having a value of empty string.
这个的回答也是这么说的.
