Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR
这个实质是Chrome问题。
我碰上的场景是后台CSS没加载成功。网页变形了。
CTRL+F5刷新无效,最后找到那个CSS文件,直接访问,再强制刷新,加载成功。
再回头刷新网页,恢复正常。

hr – Horizontal-ruleul
ul – unorder lists
element, and point to a specific image’s URL using the
attribute.
An example of this would be:
Note that
elements are self-closing.
All
elements must have an
attribute. The text inside an
attribute is used for screen readers to improve accessibility and is displayed if the image fails to load.
Note: If the image is purely decorative, using an empty
attribute is a best practice.
Ideally the
attribute should not contain special characters unless needed.
注意:img不需要加闭合, hr也是如此。
