CSS is one of the most useful ways to separate presentation coding and actual content, and is also a way to optimize search engines. Usually, a complete set of CSS style standards will be established in website design. These standards are stored in an extension in a separate file for css. Then when using HTML tags to design web pages, the content in the CSS file will be used. Three simple but very effective design techniques will guide you to correctly use CSS to improve the design of your website so that your website can rank high in most search engines.
First, consider the reality of how search engines work. After search engine robots enter the website, they browse the content on the website. Because these tools do not waste too much time searching, the easier it is for the content of the website to be searched, the better. Considering this problem, the presentation structure of some web pages is unnecessary and should be removed. It's easier to store these structures in a separate css file. This means replacing irrelevant table tags with a small number of HTML tags, because HTML tags can be better arranged using CSS rules. After removing a lot of redundant markup, only well-arranged content remains. This makes it easier for search engines to discover and index the website.
The traditional method of using images to switch between each other to achieve link effects is to use some relatively complex switching functions in JS. JS coding is not the real content to be presented on the web page, but some irrelevant language. It is very unfriendly to search engines, so if this technology is used too much in web pages to process content, it will affect the website's performance in search engines. Ranking. Using css to design web pages is a better way. Use 2 types of graphics to create text links in the web page, and use CSS to design the layout. In HTML, display the link content, design the length and width, and then define the two images as two different backgrounds. One image is displayed when the mouse leaves, and the other image appears when the mouse is clicked.
We know that search engines will focus on the titles that can be found in the search website, for example, title 1, title 2, title 3, etc. When designing title tags, what troubles many inexperienced designers is that the browser uses a lot of ugly black information to present it.
