Understanding and knowledge of web standards and websites

When writing code, you should pay attention to:

1. Label closure
2. Label lowercase
3. Cannot be nested arbitrarily

Increase the chance of being searched by search engines:

The name variable in mate "where keywords and description are particularly important"

Meta name= "Kyewords" lang= "EN" content= "Vacation,greece,sunshine"

Meta name= "Description" content= "Overview of your Page"

Meta name= "Robots" content= "all| none| Index| Noindex| follow| Nofollow "
[All: The file will be retrieved and the link on the page can be queried;
None: The file will not be retrieved and the link on the page cannot be queried; (and "Noindex, no follow" play the same role)
Index: file will be retrieved; (Let Robot/spider log in)
Follow: Links on the page can be queried;
NOINDEX: The file will not be retrieved, but the link on the page can be queried; (Do not let Robot/spider log in)
Nofollow: The file will not be retrieved and the link on the page can be queried. (Do not let the Robot/spider follow this page to look down)]

Meta name= "Author" content= "Zhang San, [email protected]"

Meta name= "Copyright" content= "This page is owned by Zerospace. All Rights Reserved "

Meta name= "Generator" content= "pcdata| Frontpage| "

META name= "Revisit-after" content= "7 Days"

Increase page load speed

1. Write JavaScript and CSS to external documents
2. Remove unnecessary spaces and comments
3. Try not to use the table layout, try to use a table layout that is not nested
4. Specify the size of the image and table
5. Try not to use images instead of text (e.g. in the navigation bar)
6. Delay the script loading and place the script at the bottom of the page
7. Try to use PNG format images
8. Check for lost files and images
