Cascading Style Sheet (CSS)

What does Cascading Style Sheet mean?

CSS are style instructions for the HTML elements of web pages. The specifications in CSS thus determine the design of HTML elements. The CSS instructions contain, for example, specifications for colours, spacing, backgrounds, fonts, styles and sizes. In most cases, the CSS styles are stored in an external CSS file. However, the CSS information can also be embedded directly in the HTML file.

What is the purpose of specifying style guides in CSS?

Thanks to CSS web pages get a uniform look. For example, all H1 headings have the same font size and color, all spacing above and below paragraphs is the same. CSS instructions make it possible to separate content and design. This allows content to be changed without affecting the design. This decoupling allows web pages to load faster. CSS supports the responsive display of HTML documents. Therefore, suitable display formats can be specified for different output devices such as desktop PC, tablet, smartphone or printer via CSS.

Does Cascading Style Sheet work with all browsers?

All common browsers support CSS. However, there are differences and limitations in the display. Therefore, test your website on all common browsers before going live!
