a:hover .inner Do you understand what this means?
This is equivalent to all under a:hover .inner
Obviously your layout does not have this relationship
Master, I understand your point of view. I used the wrong descendant selector, but what technique should I use if I want to indicate when something happens in css? Woolen cloth? For example, in my example, I want to express how the parent div displays when a is crossed over
Your parent elements are hidden and a cannot be seen. How do you make the mouse slide over?
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> <style type="text/css"> body > div { position:relative; } div > div { display:none; border:1px solid #ccc; padding:10px; } a:hover+div { display:block; } </style></head><body> <div> <a href="#">google chrome</a> <div>hello world</div> </div></body></html> The
above was not added by me.
As far as I know, I don't know of any way to select the previous element of a sibling element.
I only know about adjacent sibling selectors. Generally, sibling selectors select backwards. Like your original code, which requires selecting the previous element, I really don’t know if there is such a selector.
So the order of a and div is changed.
I finally understand clearly, dear brothers, my God, I have an urge to die.
