• Syntax proposition: readability of templated type declarations

  - by Knowing me knowing you

  I wonder if syntax as follows would be helpful in your opinion as a code readability improvent and self-commenting of code: std::map<std::string name, std::vector<int> scores> myMap; In this example it clearly says and no other comment is needed, what for we are using myMap variable. Looking forward to your opinions.

• When not to use a private field

  - by coffeeaddict

  When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.

• CSS - How can I center a div within a div?

  - by Spines

  I have an outer div that is 800px wide. I have an inner div that could be anywhere from 200 to 600px wide. I know how to center the inner div within the outer one if I set the inner one to have a specific width, but how do I center it since its a variable width? Is there a way to set the div to only be the width of the elements inside of it, rather than having it expand to fill its containing div?
