css - How do you avoid class name collisions? -


Assume that I am creating a blog and adding a class called "post" for timeline positions. Then another developer comes and creates a Highlights section, which also has a "Post" class. Suddenly we have a collision.

I usually solve it by nesting classes and do not keep anything "global", but what I have understood is that this is not the best practice: 

 < Code> .main .post {background-red color; } .highlights .post {background color: green; }   
 When I inspect the large sites CSS files, I see the weight of the global class names for the proper parts of the page, so I'm really thinking that they How to solve it. Do they search and scan the entire project for a class name before adding it? What do they do if they want to add something that already exists? For this, just changing its name really looks like bad behavior. If any

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up.
