CSS table style: 1. border-collapse style, which can set whether the borders of the table are merged into a single border; 2. border-spacing style, which specifies the distance between cell boundaries in the separated border model ; 3. Caption-side style, sets the position of the table title; 4. Empty-cells style, stipulates whether to display the borders and backgrounds on empty cells in the table; 5. table-layout style, sets the content used when completing the table layout layout algorithm.

CSS style attributes of the table
Description | CSS | |
---|---|---|
Specifies whether to merge table borders | 2 | |
Specifies the distance between adjacent cell borders | 2 | |
Specifies the position of the table title | 2 | |
Specifies whether to display the borders and backgrounds on empty cells in the table | 2 | |
Set the layout algorithm used for tables | 2 |
The border-collapse attribute sets whether the borders of the table are merged into a single border, or whether they are displayed separately like in standard HTML.
collapse | |

separate | |
inherit | |
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <style> table, td, th { border: 1px solid black; } .box { border-collapse: collapse; } </style> </head> <body> <table> <tr> <th>Firstname</th> <th>Lastname</th> </tr> <tr> <td>Peter</td> <td>Griffin</td> </tr> <tr> <td>Lois</td> <td>Griffin</td> </tr> </table><br><br> <table class="box"> <tr> <th>Firstname</th> <th>Lastname</th> </tr> <tr> <td>Peter</td> <td>Griffin</td> </tr> <tr> <td>Lois</td> <td>Griffin</td> </tr> </table> </body> </html>
(1) Function: This property specifies the distance between cell boundaries in the separated border model. This property is ignored unless border-collapse is set to separate. Although this property only applies to tables, it is inherited by all elements in the table.
Description
|
|
length length Specify the distance between the borders of adjacent cells. Use units such as px, cm, etc. Negative values are not allowed. |
If you define a length parameter, then the horizontal and vertical spacing is defined. If two length parameters are defined, then the first one sets the horizontal spacing, and the second one sets the vertical spacing. |
##3, caption-side attribute
(1) Function: Set the position of the table title. This attribute specifies the placement position of the table title relative to the table frame. The table title is displayed as if it were a block-level element before (or after) the table. (2) Possible values:
Description | |||||||||||||
Default value. Position the table title above the table. |
bottom | ||||||||||||
Position the table title below the table. |
(3) Browser compatibility: All mainstream browsers except IE support the caption-side attribute. Internet Explorer 8 (and later) supports the caption-side attribute if !DOCTYPE is specified. 4. empty-cells attribute (1) Function: This attribute defines how table cells that do not contain any content are represented. If displayed, the cell's borders and background are drawn. This property is ignored unless border-collapse is set to separate. (2) Possible values:
5. table-layout attribute (1) Function: to display the algorithm rules of table cells, rows, and columns. This attribute Specifies the layout algorithm used when completing table layout. (2) Two algorithms: Fixed table layout: fixed #Advantages: Allow the browser to layout the table faster, (in In fixed table layout, the horizontal layout only depends on the table width, column width, table border width, and cell spacing, and has nothing to do with the content of the cell. By using fixed table layout, the user agent can display the first row after receiving it Table.); #Disadvantages: Not very flexible. Automatic table layout: automatic #Advantages: More reflective of traditional HTML, (in automatic table layout, the width of the columns is determined by the fact that there are no row breaks in the column cells The widest content is set.); #Disadvantages: The automatic algorithm is slower because it needs to access all the content in the table before determining the final layout. (3) Possible values:

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.

React is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
