Fever for a few days, no updates. Would have said today to update some of the front-end framework. But someone was talking to me. I said it was too soon, let me help him comb the knowledge ahead.

First, automatic centering---the use of box models (also known as standard document flow); second, floating layout---float property to solve the floating effect; third, absolute positioning of the layout case---absolute positioning for two or more columns of layout. Have you ever heard of the standards? This is a series of standards developed by the World Wide Web Consortium, including: 1. Structured standard language (HTML and XML) 2. Performance standard language (CSS) 3. The Behavior standard language (DOM and ECMAScript) advocates structure, style, Behavior separation mechanism in CSS: there are three positioning mechanisms in CSS: 1. Standard document flow (Normoal flow) 2. Floating (float) 3. Absolute positioning (Absolute positioning) The layout of the Web page and the positioning of the page are inseparable from these three mechanisms. Here's the standard document flow: What is a standard document flow? As the name implies, documents like water. Flowing water is characterized by the flow from high to low, with width and length. The standard document flow is from left to right, top to bottom. Its characteristics are: from top to bottom, from left to right, output the contents of the document.
