parameter values, the first parameter is used on, the second argument is left and right, and the third parameter acts on the bottomWhen margin is set using a percent score, the percentage is calculated relative to the width of the parent element.Three margin foldingSome adjacent margin will merge, known as margin folding. The following example:In this example, the first H2 of Margin-bottom (10px), the DIV's margin-top (20px), the Margin-top (10px) of

(from the already dead time and again finally hung out of the Baidu space manually rescued, published on 2014-06-24)In order to eliminate the browser to the default CSS settings, keep the Web page in each browser look consistent, the initialization of CSS is very necessary! A lot of the time, the style incompatibility problem can be solved by CSS initialization code. Some common scenarios are listed below:1. The most resource-consuming, simplest2. Selective initialization example (synthesis)Body

Introduction to the Fibonacci heapThe heaps (Fibnacci heap) has two uses: First, a series of operations that form the so-called consolidated heap. Second, some of its operations can be done in constant time , making this data structure ideal for applications that require frequent calls to these operations.The Mergeable heap supports the following five operations: Make-heap (), Insert (H, X), Minmun (h), Extract-min (h), Union (H1, H2). In fact, it is

right path along the right side of the left-hand heap is indeed the shortest path in the heap. Otherwise there will be a path through a node x and get the left son, at which point the X destroys the nature of the left-hand heap.6. The basic operation of the left-hand heap is merging (inserts are only special cases of merging). The left-hand heap type declaration:Templatecomparable>class Leftistheap{public:Leftistheap();Leftistheap(const leftistheap RHS); ~Leftistheap(); BOOL IsEmpty()Const Con

B0 contains only one node BK (k> 0) composed of two tree B | K-1, one of which serves as the properties of BK of the other tree. A total of 2 ^ K Node B. the height of the tree

Use the CSS sibling selector to design the complex vertical margin (vertical margins), verticalmargins ------------------- How the sibling selector maintains CSS readability while fulfilling complex design requirements This is one of the complex examples of simple and gradual changes in web Front-end development: Applying vertical margins to all elements in an article ), for example, blog articles compiled by complex markdown. In most cases, you have to deal with many exceptions and problems. Fo

Agreed to explain the JavaScript inheritance, but delayed to now explain. No more nonsense, go straight to the point. Since you want to understand the inheritance, prove that you have a certain understanding of JavaScript-oriented objects, such as what you do not understand can refer to the object-oriented JS Basic explanation, Factory mode, constructor mode, prototype mode, mixed mode, dynamic prototype mode, The next step is to finish the JavaScript inheritance in general by those methods.

. CSS element Selector The most common CSS selector is the element selector. In other words, the document element is the most basic selector. If you set an HTML style, select The selector is usually an HTML element, such as p, h1, em, a, or even html. The following is a simple example: This is heading 1 This is heading 2 This is a common section. The browser displays the following results: From the above results, the selector priority is still selective. The html selector serves all fonts

The HTML page tags I used:SECTION,DIV,ARTICAL,P,OL,UL,LI,HEADER,FOOTER,SPAN,FORM,INPUT,LABEL,H1,H2,H3, I will not say the details, only to the novice said, why so many labels, Can you solve the whole project with only 16 of them?The reason is not to think that the label is more, we must use it, we want to use a wide, easy to remember.What does the block-level element and inline element mean, in a little explanation?The block-level element is the one t

Why do you want to initialize CSS?CSS initialization refers to the style of resetting the browser (that is, reset.css). The default styles for different browsers may vary, so the first thing to develop is how to unify them. If you do not initialize CSS, there will often be page differences between browsers. Each time the new development site or new Web page by initializing CSS style properties, for we will use the CSS or HTML tags more convenient and accurate, so that we develop the content of t
