css - Apply external stylesheet to a particular section -

-

on website allow user-generated style sheets used. don't want styles affect the whole website, separate section/div. there way that, without going through whole custom style sheet , adding div selector every css rule? example if user has:

a, span{color:white;} div{padding:10px;}

right have parse out , replace 

#mysection a, #mysection span{color:white;} #mysection div{padding:10px;}

nope, unfortunately there isn't. there no css equivalent <base> tag or similar limit scope of css rule.

you have prepend every rule element(s) want apply them to, or load user styled content in iframe.
