To use it, open a style tag within your component, use the JSX attribute, and write your CSS styles as a template literal string. With this, you can interpolate values directly inside the style tag, making it easy to change styles based on state changes. But they can be scoped to an individual component, so you don’t have to worry about naming collisions when writing your code.

what is css

You should learn the basics of HTML before attempting any CSS. We recommend that you work through our Introduction to HTML module first. The declaration what does cascading mean block (in curly braces) contains one or more declarations separated by
semicolons. This rule sets a background color for the entire page.

My First CSS Example

It still does the same job, it’s simply no longer required before an element selector. After many months of debates over how CSS Nesting could work, we ended up with the best possible solution. In the end, browser engineers figured out how to make the parsing engine handle nested type selectors (element selectors). CSS declaration always ends with a semicolon, and declaration blocks are surrounded by curly braces. But as you’re developing a web page, and you want to modify a single element, you could use inline CSS.

  • With the advent of Flexbox and Grid it has now returned to its original purpose, as this article explains.
  • CSS, or Cascading Style Sheets, is a style sheet language used for describing the presentation of a document written in a markup language.
  • Have a look at the links in this paragraph for specific examples.
  • The CSS examples are categorized based on the topics including properties, selectors, functions, and many more.
  • You’d first imagine your layout as a set number of columns (e.g., 4, 6, or 12), and then you’d fit your content columns inside these imaginary columns.
  • For existing Syncfusion users, the newest version of Essential Studio is available for download from the License and Downloads page.

Understanding the DOM helps you design, debug and maintain your CSS because the DOM is where your CSS and the document’s content meet up. When you start working with browser DevTools you will be navigating the DOM as you select items in order to see which rules apply. Each element, attribute, and piece of text in the markup language becomes a DOM node in the tree structure. The nodes are defined by their relationship to other DOM nodes. Some elements are parents of child nodes, and child nodes have siblings. After a CSS feature has been specified, then it is only useful for us in developing web pages if one or more browsers have implemented the feature.

CSS layout

These utilities eliminate the need for manual JavaScript coding, as they include features like hooks for using the intersection observer API to detect specific conditions or events. You can use them in your Next.js apps with a robust set of styles for components like buttons and cards. Utility class libraries like Tailwind and Windy CSS provide a vast collection of utility classes. The first problem you will encounter is that naming things gets complicated because of too many CSS classes. You can use a naming convention like BEM (block element modifier) to address this. To select elements with a specific class, write a period (.) character, followed by the name of the class.

Chances are, if you’ve spent any time coding, you’ve come across CSS. In short, CSS (Cascading Style Sheets) is a language that determines the style of a web document. This includes everything from the colors and fonts used to the spacing and layout of the page.
