Why do we use the DIV+CSS layout without having to pass the traditional table layout
I. The benefits of using the DIV+CSS website layout
1: Performance and content phase separation
The design part is stripped out and placed in a stand-alone style file, where only textual information is stored in the HTML file.
2: Improve indexing efficiency of search engines on Web pages
Using HTML that contains only structured content instead of nested tags, search engines will more effectively search your Web content and may give you a higher rating.
3: Improve page browsing speed
For the same page visual effect, the page size with Css+div refactoring is much smaller than that of the table-encoded paging file, which typically has only 1/2 of the latter.
4: Easy Maintenance and revision
You can redesign the entire site's pages by simply modifying a few CSS files.
From the above description, the use of Css+div to the site reconfiguration can greatly enhance the site users and search engine friendliness, css+div so become the current page layout mainstream.
Two. Use table tables to influence SEO
1. Brief introduction: Why is it unwise to use table typesetting?
The table exists in HTML only for one purpose: display tabular data. However, since then the border= "0" allows designers to put pictures and text in the invisible grid. So far, tables dominate the design of visually-rich websites, but they hinder a better, more approachable, more flexible, and more powerful approach to web design.
2. Problems caused by the form
Mix the format data into your content.
This makes the file size unnecessarily large, and users must download such formatting information once they visit each page.
Bandwidth is not free.
This makes the redesign of existing sites and content extremely labour-intensive (and expensive).
It also makes it extremely difficult and expensive to keep our entire site visually consistent.
The tabular page also greatly reduces its affinity for people with disabilities and viewers using mobile phones or PDAs.
