Now is an era that advocates structure, performance, and behavior separation. The biggest benefit is that it is easy to maintain and convenient,CodeReuse. Writing CSS and Js in HTML is like a hodgedge, which is hard to understand, has poor readability, large files, and is very difficult to maintain.
But is CSS inline or external? As long as we analyze its characteristics, it is not difficult to come up with an answer.

The C + + language supports function inline, which is designed to improve the efficiency (speed) of function execution.Benefits of macrosIn C programs, you can use macro code to improve execution efficiency.The compiler preprocessor replaces the function call by copying the macro code, saves the parameter stack, generates the call of assembly language, returns the parameter, executes the return and so on, thus improves the speed.Disadvantages of macro
This is because the inline element and the Inline-block default will have the spacing, how to remove the default distance?1: with floating float:left;2: Set the child element font, and then set the parent element font-size:0px (this method can not be used when floating in the use of a very useful)3: Closed label between related tags do not wrap (this maintenance is more troublesome, the program apes may not

Display: block is a block-level element.
Height, row height, and margin can be controlled
The default width is 100% of its container, unless a width is set.
Demo:
Display: inline is a row element.
And other elements are on one line;High, the Row Height and top and bottom margins cannot be changed;
The width of a text or image cannot be changed.

Inline functions are executed in much the same ways as with parametric macro definitions, but the parameters are handled differently. Macro definitions with parameters do not perform an operation on the parameters, but instead directly replace the

1. Inline functionsIn C + + we typically define the following function to find the maximum value of two integers:int max (int a, int b) { return a > B? a:b;} The benefits of defining a function for such a small operation are:① reading and understanding the invocation of the function max is much easier than reading an equivalent conditional expression and explaining its meaning.② If you need to make any changes, it's much easier to modify the func

This article introduces the differences between inline usage in GCC and c99. When using the inline attribute, pay attention to the following two points: the inline keyword is only described in the definition of the function used in the GCC reference document, it does not mention whethe
inline and block-level elements
inline elements are generally containers of content, while block-level elements are generally containers for other containers . In general, inline elements can only contain content or other inline elements. Width and length are based on content, can not be set, can coexist with other el
I've always thought that the inline keyword is in C + +. Today I saw an article about the C language of the inline keyword. Oh...It turns out I made a mistake. It seems that some macro commands can be replaced with some inline functions in the future.
