css - How can we keep the font scaling up and down but make it not so context sensitive? -

-

deep project having problems use of em's in our font-size. have several markup modules reusing in different contexts. constant head aches calculated font-size being different in different contexts. using em's important using responsive design. scalability of font-size must have. please see jsfiddle simple example. how can keep font scaling , down make not context sensitive?

inheritance can quite annoying, espcially when working ems. know context class names should able overcome problem applying simple maths.

let's take in .context1 ideal, css looks like:

.context1 {     font-size: 1em; } .context2 {     font-size: 1.5em; } .my-font-size {     font-size: 3em; }

in case, first heading 3em, second 4.5em because parent defined being 1.5x bigger. around this, following:

.context1 {     font-size: 1em;    //default font size .context1 } .context2 {     font-size: 1.5em;  //default font size .context2 } .my-font-size {     font-size: 3em;    //default font size .my-font-size } .context2 .my-font-size {     font-size: 2em;    //adjust font size parent's value (3/1.5) }

similarly, define .context2 norm:

.context1 .my-font-size {     font-size: 4.5em;    //(3 * 1.5) }

here's updated example.

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
