What codes should I master when learning web page design?

This article introduces in detail some of the techniques that should be mastered in the process of learning web page production. It is best to learn and study these contents step by step and never skip them. However, the webmaster of 123WORDPRESS.COM recommends that new students can create a website as long as they master the first three items! They are: HTML, CSS and XHTML. At least there is no problem making a web page! This article only introduces some codes that you should master. If you want to realize exquisite web pages, you need to master some application skills of graphics software! If you want to develop interactive websites with complete functions, then you need to master some basic programming knowledge. If you have any questions, feel free to ask me! Thanks! HTML 4.01
HTML is the language of the Web, and every Web developer needs to have a basic understanding of it.
HTML 4.01 is an important web standard that differs significantly from HTML 3.2.
When tags like font and color attributes were added to HTML 3.2, it started to become a nightmare for developers. The process of developing websites where font information had to be added to every single page became a long and expensive ordeal.
With HTML 4.01, all formatting information can be moved out of the HTML document and placed into a separate style sheet.
Another reason why HTML 4.01 is important is because XHTML 1.0, the latest HTML standard, is HTML 4.01 reformulated as an XML application. Using HTML 4.01 in your pages ensures that HTML can be easily upgraded to XHTML in the future.
Please make sure you are using the latest HTML 4.01 standard.

Cascading Style Sheets (CSS)
Styles define how HTML elements are displayed, similar to the role played by the font tag in HTML 3.2. Styles are usually stored in files outside of the HTML document. External style sheets give you the ability to change the look and layout of all the pages on your website simply by editing a simple CSS document. If you've ever tried to make a change, such as changing the font or color of all the page titles on your site at once, you'll understand how CSS can help you do more with less.

XHTML - The Future of HTML
XHTML refers to Extensible HyperText Markup Language.
XHTML 1.0 is the latest HTML standard from the W3C. It became an official recommendation on January 26, 2000. W3C Recommendation means the stability of its specifications, and its specifications have now become a Web standard.
XHTML is a reformulation of HTML 4.01 using XML and can be used immediately in existing browsers by following some simple guidelines.

XML - A tool for describing data Extensible Markup Language (XML) is not a replacement for HTML. In future web development, XML will be used to describe and store data, while HTML will be used to display data.
The most appropriate description of XML is that it is a cross-platform, hardware- and software-independent information storage and transmission tool.
We believe that XML is as important as HTML is to the web, and that XML will become the most important tool for data processing and transmission.

XSLT - a tool for users to transform data
XSLT (Extensible Stylesheet Language Transformations) is a language used to transform XML.
Future websites will have to deliver data in different formats to different browsers and to other web servers. XSLT is a new W3C standard for transforming XML data into different formats.
XSLT can transform XML documents into a format that browsers can understand, such as HTML, or WML - a markup language used by many handheld devices.
XSLT can also add elements, delete elements, rearrange and sort elements, test and determine which elements are displayed, and so on.

Client-side scripting Client-side scripting is a type of programming that affects the behavior of Internet browsers. You should learn JavaScript so you can deliver more dynamic website content:

JavaScript is a programming tool provided for HTML designers. HTML creators are usually not programmers, but JavaScript is a scripting language with very simple syntax! Almost anyone can drop some JavaScript snippets into their HTML pages. JavaScript can put dynamic text in HTML pages. A JavaScript line like this can write variable text in an HTML page: document.write("h1" name "/h1") JavaScript can respond to events. JavaScript can be set to occur when an event is executed, such as when the page loads or when a user clicks on an HTML element. JavaScript can read and modify HTML elements JavaScript can read and modify the contents of HTML elements JavaScript can be used to validate data You can use JavaScript to validate form data before the form is submitted to the server, thus ensuring that the server processes the data correctly.

Server-side scripting Server-side scripting is related to Internet server programming. You should learn server-side scripting so that you can deliver more dynamic website content. Through server-side programming, you can: dynamically edit, modify, or add web page content respond to user queries or data submitted from HTML access data or databases, and return the results to the browser access files or XML data, and return the results to the browser convert XML to HTML, and return the results to the browser customize pages for different users and improve page usability provide security and access control for different web pages design different outputs for different types of browsers minimize network traffic

Managing Data with SQL Structured Query Language (SQL) is the universal standard for accessing databases such as: SQL Server, Oracle, Sybase, and Access.
Knowledge of SQL is extremely valuable for anyone who wishes to store and retrieve data from a database.
Any web administrator should understand that SQL is a truly relevant engine for databases on the web.
