In daily learning, we have learned HTML, CSS and JS. At first, we could not distinguish the difference and connection between the three. With the increase of knowledge, we have some experience. With the qianfeng Chongqing Web front-end xiaobian take a look at these three technologies are what, what can be done?
Web front-end engineer is a new career that has only been developed in recent years, and it is also a hot and high-paying job now. Different companies use different terms, such as web interface development, web design, and so on. What do YOU need to know to learn about Web front-end development? Qianfeng Chongqing Web front-end xiaobian summarized, must master is the following points.
1. HTML — Hypertext Markup Language
Hypertext Markup Language. It marks various parts of the web page to be displayed through markup symbols. The web file itself is a text file, and by adding tags to the text file, you can tell the browser how to display the content (for example, how to handle the text, how to arrange the screen, how to display the image, etc.).
Browsers read web files sequentially, then interpret and display the contents of their tags according to the tags,
2, 2CSS – Cascading Style Sheet
Cascading style sheets. Is a markup language that separates style information from web page content. In the brisket press release system, we used CSS files to modify the style of some tags.
Alt =” sizing: border-box “style=”box-sizing: border-box; Padding – top: 0.6 rem; Padding – bottom: 1.5 rem; list-style: none; border-width: 0px; border-style: initial; border-color: initial; outline: none; vertical-align: middle;” “Class =” data – thewire = “0.4078125” data – w = “640” data – type = “jpeg” >
In plain English, CSS is the language for setting the attributes of HTML elements on a web page.
3, JavaScript,
Why is the name so similar to Java? It was a classic marketing success, and it took Java to its credit. When Microsoft began to realize that Javascript was popular among Web developers, it did what it always did and created its own scripting language, JScript.
Javascript is an object-based and event-driven scripting language with security performance. The purpose of using it is to link multiple objects in a Web page and interact with Web customers together with HTML hypertext Markup Language and Java scripting language (Java applets). For example, you can set mouse hover effects, validate forms on the client side, create custom HTML pages, display warning boxes, set cookies, and more. Function jsHello{alert(‘Hello World! ‘); } embed the code in THE HTML language and it will pop up a “Hello World” dialog box at load time. As for how to embed, we already know at the beginning of learning JS video.
