What is a stylesheet? What are the benefits of using stylesheets

A style sheet is a regular collection of all styles into one. css table. If you have the same style on the page, you don't need to copy a piece of style to the page, you just need to import the CSS table and then reference it.

And it is also more convenient when modifying, as long as one is modified. CSS stylesheet files are sufficient, and there is no need to modify them one by one.

The style sheet is CSS, and some of the formatting content of the page can be defined in the style sheet, so that there will be no miscellaneous definitions of styles in your HTML page, so that the separation of structure and performance can be well achieved, which is more in line with web standards.

The benefits of using CSS stylesheets are:

2. Using the attribute inheritance method, you can easily maintain different styles of the same markup;

3. Content with a higher rate;

4. The page loads very quickly;

5. Define the flexibility of style.

Knowledge Supplement:

CSS stands for Cascading Style Sheet, which stands for Cascading Style Sheet.

CSS is used to improve the rendering of HTML markup content. Using CSS, we can define different ways to display content based on **.

Pros of CSS:

First, there are fewer CSS.

You can define properties with values in a common style class, and you can use the same class in different places, so you can use fewer ** to achieve more functionality. Less means less bandwidth consumption and easier content maintenance.

Second, easy to maintain.

When styles are defined globally or in common, any variation becomes easy to manipulate. For example, in **, display all the names of a product using a specific style attribute. You can now change the style throughout your site by changing the style class for the product name in an external style sheet.

You can keep multiple stylesheets and use them as needed. Using the property inheritance method, you can easily maintain different styles of the same tag.

3. Content with a higher (tag) ratio.

Higher proportional content can be achieved in the page by using CSS, as style declarations can be converted to external files. This is important for the search engine's point of view. Spiders can be provided with fewer tags (style tags) and more content for indexing.

When the browser caches a stylesheet page, the page loads quickly. Every time a different page of the same site using the same CSS, the style class is not loaded from the server.

5. Define the flexibility of style.

Name cascade means that multiple styles can be used, and local styles are prioritized. You can override the declared global style and assign the style locally to the tag.

CSS style sheet is to write some reused style effects into the CSS file, and you can call it directly with class or id in the page, which is convenient to use and easier to manage.

Style sheets are CSS, and web pages are beautiful.
