Classification of HTML tags
When talking about label classification, we as beginners in the first use of the label will find some properties on some labels do not work, such as wide, high, horizontal center, in fact, the use of this property is only used on block-level labels to function. Personally, this is a very easy place for beginners to overlook, so I'll write it down!
First, we can divide the HTML tags into: block-level labels, inline tags,
In CSS, tag elements in HTML are broadly divided into three different types: block elements, inline elements (also called inline elements), and inline block elements.1, block elementThe most common block elements are:What is a block-level element? In HTML display:blockthe setting is to display the element as a block-level element. The following code is the conver
First, the key:1,Inline functions are the same in readability as functions, while at compile time the functions are embedded directly into the body of the caller, eliminating the call/return instruction, which is faster at run time.
2,Inline functions can be debugged, and macro definitions cannot be debugged.
Inline functions and macros are essentially two diff
When we use firbug to browse other websites, we will find that designers use inline-block in many places. We all know that inline declares that div is an inline object and block is a block object. What does inline-block mean? Next, let's test the differences and functions of the three:

1. inline functions are static actions, while virtual functions are dynamic actions, which are in conflict.2. We can see some virtual functions like inline functions, because whether a function is an inline function is determined by the compiler rather than the calculation. We can only advise the compiler that a function can be an

The inline keyword is similar to macro, where the compiler places a new copy of the inline function where it is called, and the
