問題描述
我正在為我的所有圖像添加 alt 屬性以提高 SEO/屏幕閱讀器性能.
I'm adding alt attributes to all my images to improve SEO/screen reader performance.
根據最佳實踐，純美學圖像應該有一個空的 alt 屬性 alt=""，以便屏幕閱讀器跳過它們.我在 WordPress 中發現它確實將 alt 添加到這些無描述的美學圖像中，但沒有添加 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="".
屏幕閱讀器和搜索引擎爬蟲讀取 alt 是否與 alt="" 相同，或者我應該進入并以編程方式強制 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=""?
推薦答案
是的，都一樣:https://www.w3.org/TR/html5/syntax.html#attributes-0
空屬性語法
只是屬性名稱.該值隱含為空字符串.
Just the attribute name. The value is implicitly the empty string.
對我來說，這就是說沒有值的屬性與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.
這個的回答也是這么說的.
