在学习完牛腩新闻发布系统之后,才发现自己每天浏览的网页是怎么来的。原来,看起来很高大上的网页自己也可以做得有模有样。 其实,牛腩的学习正是米老师一直给我们强调的各种学习方法的映射。因为它其中包含着太丰富的知识,刚开始的我们或许都很迷茫,也就只能是照着视频一步步照做,这样一个过程其实就是一个囫囵吞枣的阶段,对于学习的知识点,有个大概印象就好。 接下来的学习,应该就是具体知识细节的学习了。 第一个就是HTML,一个短短两个小时的资料,自己也是感觉收获颇多。很基础的知识,在牛腩中大都接触过,但当时自己不清楚什么是什么。通过这次视频的学习,和牛腩新闻发布系统产生了很多共鸣。 HTML的知识很简单,也很基础。HTML,超文本标记语言,标准通用标记语言下的一个应用。Web网页也是一种文档,HTML就是用于编写这种文档的标记语言。 视频中主要是从以下几个方面进行了简单讲解:
<pre class='brush:php;toolbar:false;'> 对于我们来说,这些并不算是陌生,在牛腩中也是重复敲了很多遍了。可能刚开始都不知道叫什么,而通过这个视频的学习,应该专业了许多。 在视频中,还认识了“表单”。 表单是一个包含表单元素的区域。表单元素是允许用户在表单中(比如:文本域、下拉列表、单选框、复选框等等)输入信息的元素。表单使用表单标签(<form>)定义。 多数情况下被用到的表单标签是输入标签(<input>)。输入类型是由类型属性(type)定义的。 表单标签:
<pre class='brush:php;toolbar:false;'> 在HTML定义中,“超文本”就是指页面内可以包含图片、链接,甚至音乐、程序等非文字元素。那么,如何来添加这些非文字元素呢? <strong>添加超链接:</strong> 语法格式:<a href="URL">...</a>. URL,统一资源定位符是对可以从互联网上得到的资源的位置和访问方法的一种简洁的表示,是互联网上标准资源的地址。 属性href用于指定链接的目标,目标地址由URL定位,在开始标签<a>和结束标签</a>之间输入的文本将作为浏览器中显示的链接文本。 实例:<a href="www.baidu.com">百度首页</a> <strong>添加图片:</strong> 语法格式:<img src="/static/imghwm/default1.png" data-src="URL" class="lazy" style="max-width:90%"HTML, it turns out they_html/css_WEB-ITnose" > 属性src指定图像资源的位置,属性width和height用于指定图片的尺寸。 <strong>学习心得:</strong> 学习完孙鑫老师的HTML视频课程后,积累了很多点滴,很基础,也很重要。在牛腩中虽然都敲过这些代码,但始终不知道叫什么,这岂不是不专业了。就好像遇见一个人,虽然认识,但叫不上名字,那岂不是会惹得别人不高兴了。哈哈~ B/S学习继续

The function of HTML is to define the structure and content of a web page, and its purpose is to provide a standardized way to display information. 1) HTML organizes various parts of the web page through tags and attributes, such as titles and paragraphs. 2) It supports the separation of content and performance and improves maintenance efficiency. 3) HTML is extensible, allowing custom tags to enhance SEO.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.

HTML is a language used to build web pages, defining web page structure and content through tags and attributes. 1) HTML organizes document structure through tags, such as,. 2) The browser parses HTML to build the DOM and renders the web page. 3) New features of HTML5, such as, enhance multimedia functions. 4) Common errors include unclosed labels and unquoted attribute values. 5) Optimization suggestions include using semantic tags and reducing file size.
