Are you learning CSS layout? Are you still unable to fully master pure CSS layout? There are usually two situations that hinder your learning:
The first possibility is that you haven't understood the principle of CSS processing pages. Before you consider the overall performance of your page, you should first consider the semantics and structure of the content, and then add CSS for the semantics and structure. This article will tell you how to structure HTML.
Another reason is that you are at a loss for those very familiar presentation layer attributes (such as cellpadding, hspace, align="left", etc.) and don't know what CSS statements to convert them into. Once you have solved the first problem and know how to structure your HTML, I will give you a list detailing what CSS to use to replace the original presentation attributes.
Structured HTML
When we first learn web page production, we always consider how to design it first, considering the pictures, fonts, colors, and layout plans. Then we use Photoshop or Fireworks to draw it and cut it into small pictures. Finally, edit the HTML to restore all the designs to the page.
If you want your HTML page to be laid out with CSS (CSS-friendly), you need to go back and start over. Don't think about "appearance" first, but first think about the semantics and structure of your page content.
Appearance is not the most important thing. A well-structured HTML page can be presented in any appearance, and CSS Zen Garden is a classic example. CSS Zen Garden helps us finally realize the power of CSS.
HTML isn't just for reading on a computer screen. Your carefully designed images in Photoshop may not be displayed on PDAs, mobile phones, and screen readers. But a well-structured HTML page can be displayed anywhere and on any network device through different definitions of CSS.
start thinking
The first thing to learn is what "structure" is, which some writers also call "semantics". What this term means is that you need to analyze your content blocks and the purpose each piece of content serves, and then build the corresponding HTML structure based on these content purposes.
If you sit down and carefully analyze and plan your page structure, you might end up with something like this:
Logo and site name
Main page content
Site Navigation (Main Menu)
submenu
search box
Functional areas (e.g. shopping cart, checkout)
Footer (copyright and related legal notices)
We usually use DIV elements to define these structures, similar to this:
| The following is the quoted content: ＜div id="header"＞＜/div＞ ＜div id="content"＞＜/div＞ ＜div id="globalnav"＞＜/div＞ ＜div id="subnav"＞＜/div＞ ＜div id="search"＞＜/div＞ ＜div id="shop"＞＜/div＞ ＜div id="footer"＞＜/div＞ |
