What do you mean by CSS?

CSS stands for Cascading Style Sheets. It is a stylesheet language used for describing the look and formatting of a document written in HTML or XML. CSS allows developers to separate the presentation of a document from its structure and content, enabling greater control over the appearance and layout of web pages. CSS is applied to HTML elements by using selectors to target the elements, and then applying properties and values that dictate how those elements should be styled. This can include colors, fonts, spacing, and more. CSS can be included within an HTML document, placed in an external stylesheet file that is linked to the HTML, or embedded directly in the HTML elements themselves. One of the key benefits of CSS is its ability to maintain consistency across multiple web pages. By using external stylesheets, developers can apply the same set of styles to an entire website, which can save time and ensure a uniform look and feel. Here's the translation of the above explanation into Chinese: CSS 是 Cascading Style Sheets 的缩写，它是一种样式表语言，用于描述 HTML 或 XML 编写的文档的外观和格式。CSS 允许开发者将文档的结构和内容与其表现形式分离，从而更有效地控制网页的外观和布局。 CSS 通过使用选择器来应用样式，选择器用于定位 HTML 元素，然后应用属性和值来决定这些元素应该如何被样式化。这包括颜色、字体、间距等。CSS 可以包含在 HTML 文档中，放置在链接到 HTML 的外部样式表文件中，或者直接嵌入到 HTML 元素本身。 CSS 的一个关键优势是能够跨多个网页保持一致性。通过使用外部样式表，开发者可以对整个网站应用同一套样式，这可以节省时间并确保统一的外观和感觉。
