You can write js to change it, but if there are many layers of loop operations, you need to write a large section of js. At this time, js is not the best choice. What you really need is the 'unset' attribute

If unset is set for a certain keyword, such as color: unset; it will first choose to inherit the parent's attributes, and then choose to inherit its own attribute value, that is: inherit > initial

title title title
 text text text 

CSS:

p{ color:red; } span{ color:blue; } .h_bg{ color:#FFF; background:#DEDEDE; padding:20px; text-align:center; width:200px; height:200px; } .reset{ color:unset; //去掉这个属性，文字会优先使用span和P的color值 }
