In this case style.css is located in root of the theme's folder function themeSlug_enqueue_scripts() { wp_enqueue_style( 'themeSlug-style', get_template_directory_uri() .'/style.css', '1.0.0'); } add_action('wp_enqueue_scripts', 'themeSlug_enqueue_scripts');

In this example we want to include font awesome icon font function themeSlug_enqueue_scripts() { wp_enqueue_style( 'font-awesome', '//cdnjs.cloudflare.com/ajax/libs/font-awesome/4.6.3/css/font-awesome.css'); } add_action('wp_enqueue_scripts', 'themeSlug_enqueue_scripts');

Functions are only useful if we can call them. To call a function the following syntax is used: print("Hello, World!") We're calling the print function. Using the argument "Hello, World". As is obvious, this will print Hello, World to the output stream. The returned value is ...

function sayHello(name) print("Hello, " .. name .. "!") end That function is a simple function, and it works well. But what would happen if we just called sayHello()? stdin:2: attempt to concatenate local 'name' (a nil value) stack traceback: stdin:2: in function ...

Functions in Lua can return multiple results. For example: function triple(x) return x, x, x end When calling a function, to save these values, you must use the following syntax: local a, b, c = triple(5) Which will result in a = b = c = 5 in this case. It is also possible to ignore r...

Implementations in classes, including abstract declarations, take precedence over all interface defaults. Abstract class method takes precedence over Interface Default Method. public interface Swim { default void backStroke() { System.out.println("Swim.backStroke"); ...

Macros return code. Since code in Lisp consists of lists, one can use the regular list manipulation functions to generate it. ;; A pointless macro (defmacro echo (form) (list 'progn (list 'format t "Form: ~a~%" (list 'quote form)) form)) This is often very hard to...

The expansion of a macro often needs to use symbols that weren't passed as arguments by the user (as names for local variables, for example). One must make sure that such symbols cannot conflict with a symbol that the user is using in the surrounding code. This is usually achieved by using GENSYM, ...

Multiple transforms can be applied to an element in one property like this: transform: rotate(15deg) translateX(200px); This will rotate the element 15 degrees clockwise and then translate it 200px to the right. In chained transforms, the coordinate system moves with the element. This means tha...
