说在前面：

嗯...博主现在是大一，前段时间犯脑癌想开一个技术博，记录一下学习过程，也是这么做的。

为什么要学前端呢？无非就是为了走在发家致富，迎娶白富美的康庄大道上。那几周来对前端开发已经入门了，（鼓掌，鼓掌）非常有意思。但还是感觉道阻且长。不懂的东西越来越多......不过还好，有好多人帮我呀，ありがとう。

html+css+js，入门很容易。读过网页设计的书也感觉OK。(捂脸，折腾小一个月还是有战果的)，希望懒癌远离我，让我坚持把博客写下去。

从这周开始对学过的HTML5和CSS，开始梳理一下知识点（我觉得重要的标签，今天先写一部分）。

头：

标签：定义在

标签中。用于定义网页的信息。

下面是一些总结：

音频文件为什么不响？

原因：编译器不识别我引入的音频文件的格式，要在编译器里确定音频文件的格式为.mp3。

Difficulty in updating caching of official account web pages: How to avoid the old cache affecting the user experience after version update? Mar 04, 2025 pm 12:32 PM

The official account web page update cache, this thing is simple and simple, and it is complicated enough to drink a pot of it. You worked hard to update the official account article, but the user still opened the old version. Who can bear the taste? In this article, let’s take a look at the twists and turns behind this and how to solve this problem gracefully. After reading it, you can easily deal with various caching problems, allowing your users to always experience the freshest content. Let’s talk about the basics first. To put it bluntly, in order to improve access speed, the browser or server stores some static resources (such as pictures, CSS, JS) or page content. Next time you access it, you can directly retrieve it from the cache without having to download it again, and it is naturally fast. But this thing is also a double-edged sword.
