Modify the style that comes with vant
Today, when writing a page with vue, I found that some UI components of vant can not meet their own style, and it is still invalid to modify the CSS style.
Css generally uses sass or less, and the modified style does not work after adding scoped, even if important is added.
In a vue project, when the style tag has a scoped attribute, its CSS style only acts on the elements in the current component, and the style of the parent component will not infiltrate the child component.
Solution.
1. Works for css syntax
Using the depth selector, use the > operator to "drill down" the selector in the scoped style, that is, to affect the subcomponents
The above code will be compiled into:
two。 For preprocessors such as scss,less
Use the / deep/ operator instead-- this is an alias for >
The code is as follows:
In this way, the modification of the style is effective.
Why can't the style of vant be modified?
When writing in vue, add this scoped to avoid global pollution.
But adding scoped makes it impossible to modify the style in the vant framework component itself, but we can't remove the scoped.
Even if we can't write the style in vant, we can't get rid of it, so how can we implement the style without removing it?
If there is a scss, just add / deep/ to the original style class.
/ deep/. Van-cell {background: # F39894; color: white;} / deep/. Van-icon::before {color: white;}
In this way, you can modify the style of the component even if you have scoped.
