CSS class priorities

由 為{幸葍}努か 提交于 2019-12-28 11:54:13
问题 I have a question about the priority of CSS classes after encountering a problem today. The situation is as follows: I have an unordered list which has a class associated with it. The LI tags have some styles defined too. I want to change the styling of the LI s after a click (via an added "selected" class), but the added class's styles are never applied. Is this normal behavior or should this code work? CSS: .dynamicList { list-style: none; } .dynamicList li { display: block; width: 400px;

问题 How does CSS determine when to apply one style over another? I have been through the W3 CSS3 selectors document a few times, and that has helped me understand how to better use CSS selectors in jQuery, but it has not really helped me understand when one CSS rule will be applied over another.

CSS Specificity - Defining Classes & IDs

由 半腔热情 提交于 2019-12-23 01:36:14
问题 I've been reading up on specificity and, quite frankly, I'm surprised that I didn't know about this properly before, since I've witnessed the very issues that specificity can give if CSS is declared in the wrong manner. So, I've been doing a little research on the subject, and I now understand the rule for calculating specificity. However, during my findings, I've been left with three questions which I was hoping you guys could help me out with. Firstly, when relating to CSS specificity, I've

CSS rules output by SASS mixin being ignored

问题 A SASS mixin which produces some CSS rules is being ignored. Chrome Dev Tools is showing the rules registered but crossed out and I cannot figure out why.
