Hello guys I have this CSS selector and I can't figure out how to read it. Can someone explain? Thanks
.form__input:not(:placeholder-shown).form__input:not(:focus)+.form__label {
The ideal is that in nested css classes you put them one below the other for easy reading, since it can contain many elements and about your question
.form__input:not(:placeholder-shown)
// apply the class to all .form__input that do not have the selector "placeholder-shown".
.form__input:not(:focus) // applies the css to all .form__input not in "focus".
+.form__label // here applies the css to the input label
{

With-respect to the following expression:
radio:focus > .approve, radio:focus > .dis-approve{/*statements...*/}
Is it accepted by CSS interpreter/compiler?
Objective: applies iff both .approve and .dis-approves' radio-typed parents are in-focus.
It is valid (see BoltClock's comment), but you'll find that it will not match anything as it has several problems:
radio isn't a valid HTML element. Did you mean input[type=radio]?
If you did mean input[type=radio], that element cannot have children, so > .approve and > .dis-approve wouldn't select anything. Did you mean + .approve and + .dis-approve, to an element next to this one?
The best way to know if your CSS works is to apply your CSS to a HTML structure which should accompany this and see what happens.

For a responsive website is there a best practice to hide/show elements altogether in a media selector? E.g. is it better to have a class called .hide_on_desktop (which sets display: none;) and then to add that class to several elements in the website using HTML.
Or to do the following:
.element1, .element2, #element3{
display: none;
}
In the above case element1, element2 and element3 are selectors (classes and ids) that already exist.
Which approach is best for a big website?
I would suggest creating a hidden class if you plan to hide several objects. Bootstrap handles this by having classes: .hidden-xs, .hidden-sm, .hidden-md,etc.. in order to hide elements based on device width.

How does the
not(#foo)
selector works to block older browsers and for which browsers does it work in the following tutorial?
http://css-tricks.com/snippets/css/custom-checkboxes-and-radio-buttons/
The CSS selector does not block browser, it's just not supported by the browser, i.e. when CSS file is being parsed by browser's built-in parser (which in turn supports certain CSS specification), unknown selectors and rules will be ignored and won't be added into styles of frames in render tree

maybe a silly question but as far as I like standards I'd like to know, how should we write CSS selectors:
.my-selector-for-div (breaks)
.mySelectorForDiv (camel case)
Is there a standard which of those ( or any other ) should be used ?
Here is a website of css name convention (with examples):
http://www.realdealmarketing.net/docs/css-coding-style.php
There are some interesting articles about code formating (about CSS and BEM methodology):
http://csswizardry.com/2013/01/mindbemding-getting-your-head-round-bem-syntax/
http://coding.smashingmagazine.com/2012/04/16/a-new-front-end-methodology-bem/
I'd go with matching the language. In CSS' case it uses hyphenation regularly so for selectors I would also use hyphens even though I personally find them ugly.
Not sure if there's a proper style guide for them though.
edit: Can I use camel-case in CSS class names seems to also say use hyphens for class names.
