Implementation method of multi-column layout in front-end development
This time I will bring you the implementation method of multi-column layout in front-end development. What are the precautions for implementing multi-column layout in front-end development. The following is a practical case, let's take a look.
Multiple column layout
Multi-column layout is also relatively common in web front-end development, such as the common three columns, four columns and above. The column layout allows a single page to display more categorized content. The multi-column layouts mentioned here include two columns with fixed width and one adaptive column, multiple columns with variable width and one adaptive column, and multi-column layout.
Two columns with fixed width and one column with adaptive layout
This layout mode is divided into three columns, two of which have a fixed width, and one column whose width changes with the width of the content.
Two columns of fixed width plus one adaptive column
In this case, the height of each column is adaptive, that is, the height is consistent with the height of the content. The width of the left column and the middle column is 100px, and the width of the right column is adaptive. It is achieved through floatfloating layout combined with the characteristics of block-level elements. accomplish. It should be noted that the background color can be set on the p tag or on the p tag.
Multiple columns with variable width plus one column adaptive
The case explained here is a highly adaptive layout scheme with two columns of variable width and one adaptive column,
Here are multiple columns of variable width plus one adaptive column
The first thing to understand is variable width. Variable width means that the width of the column can be set to other values at any time. Here we can set the width of the column in the left column to any value without changing the layout mode, so we see The code to implement this layout is the same as above. What needs to be noted is the difference between variable width and adaptive width.
Multiple column equal parts
The multi-column layout is to display multiple columns on the page. The widths of these columns are consistent, the spacing is consistent, and the height is adaptive.
Easy implementation of multi-column distribution layout
Set margin-left to -20px on the parent container, add 20px to the width of the parent container, set left floating on the column container, and set the width of each child container to 25% of the parent container, and at the same time Set the subcontainer padding-left to 20px, and the display mode to border-box (the width and height of the box model displayed in this realistic mode are the width and height of the box). This solution achieves equal distribution by increasing the width of the parent container by 20px (gap width), displaying the spacing inside the child container, and setting the child container as a border box.
This article only lists the solutions to implement multi-column layout through float. There are also corresponding implementation solutions through flex, table, etc.
I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

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),

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
