the object is the object type. The object types include object, function, String, number, Boolean, array, Regexp, date, globel, math, and error, and the object types provided by the host environment. Except for reference, list, and completion, these answers are similar. 2. What are the similarities and differences between alt and title? I saw such an article a few days ago. These two attributes are repeated. The performance varies in different browsers. When both ALT and title are set, ALT is

These two properties are somewhat repetitive. There are some differences in different

margin is PX. That is to say, auto is used to "fill" the required distance so that the total width of the element is equal to the width of its contained block. .container1 p{background: #ccc;margin-right: auto;margin-left: auto;width: 100px; } The effect is as follows: Therefore, if you set both margin-left and margin-right to auto: Setting the two margins to an equal length is a correct way to center an element. This is different from using text-align (text-align only applies inline content

there is no problem after the object is set. Why Display:inline can solve this bilateral bug, first of all the inline element or inline-block element is no bilateral distance problem. Then, floating properties such as float:left allow the inline element to haslayout, allowing the inline element to behave like inline-block elements, supporting high widths, vertical margin, and padding, so div All the styles of class can be used on this display inline element.Floating element 3px interval bug in

, while low-end products could be free; it could take months to build a high-end firewall from scratch. In addition, the system administration overhead is also a problem to consider. Building a home-grown firewall is good, but it is important that the firewall does not require high maintenance and update costs. Reflect the enterprise's system strategy It personnel need to understand that the post-installation firewall is intended to be explicitly rejected-except for all services that are criti

is 400px, set the left margin to auto, then the width of the left margin will be 200px. That is, auto is used to "fill" the required distance, so that the total width of the element is equal to the width of its containing block.. Container1 P {background: #ccc; margin-right: auto;margin-left: auto; width: 100px; }The effect is as follows:Therefore, if both Margin-left and Margin-right are set to Auto:Setting the two margins to equal length is the correct way to center the element, unlike using

image problem, you can integrate all the small images into a large image, such: 　　 This can be 20 to 1 A number of connections, in addition to reducing the number of connections, can speed up the page to load pictures, here I suggest you save as a png-8 format, because it is gif, jpg, png-32 to be smaller, it means that you load the page faster, users can see your site content faster, one stone two birds. Learn how to call these images: For example, to call the member login icon On the page:

IE6 Common Bugs and ie6bugs 1. IE6 weird parsing: Calculation of padding and border into width and heightCause: Non-box model Parsing is caused by no document DeclarationSolution: add the Document declaration. 2. IE6 doubles the margin value when the block element, left and right float, and marin is set (bilateral distance)Solution: display: inline 3. The following three types are actually the same bug, but they are not actually a bug. For example:
