- Implementing HTML `charset` for Unicode Support
- To solve the problem of garbled web pages, you need to ensure that the HTML charset is set correctly. First, the HTML file itself must be saved as UTF-8 encoding, otherwise garbled code will appear even if it is written; secondly, it should be placed at the front of HTML to avoid parsing errors caused by browser guessing encoding; finally, the server also needs to configure the correct Content-Type, such as Apache adds AddDefaultCharsetUTF-8, and Nginx configures charsetf-8 to ensure that the character set declared in the HTTP header is consistent with the page, and avoid inconsistent encoding of the front and back ends causing garbled code.

- HTML `importance` Attribute for Resource Prioritization
- The importance attribute is an attribute in HTML that specifies resource loading priority. It supports three values: high, low and auto. It can be used for tags such as, ,, etc. By setting the importance level, developers can control the order of resource loading, such as setting critical CSS or home screen image to high, and setting non-critical scripts or lazy loading resources to low, thereby optimizing page loading performance. It should be noted that not all browsers fully support this property. Currently, the Chromium kernel browser supports it well. It is recommended to use it in combination with other optimization methods such as lazy loading, resource splitting, etc., and monitor the loading effect through DevTools. Rational use of importance can improve user experience, but abuse of hi should be avoided.

Load resources asynchronously, place JS at the bottom, use async and defer attributes reasonably, and delay loading non-first-screen content; 4. Use the caching mechanism, set the Cache-Control header and manage the cache strategy in combination with CDN. These optimization methods can effectively improve HTML performance and speed up page loading and rendering.
