terminology What is the meaning of “cascading” in CSS?

CSS lets you stylize everything on a different file, thus creating the design there and later on integrating the CSS files on top of the HTML markup. This makes the actual HTML markup much cleaner what is css and easier to maintain. CSS is not technically a necessity, but you probably wouldn’t want to look at a web page that features only HTML elements as it would look completely bare-boned.

This causes the first frame of the animation to have the header drawn off the right edge of the browser window. In this second example, three animation names are set, but there’s only one duration and iteration count. In this case, all three animations are given the same duration and iteration count. CSS animations make it possible to animate transitions from one CSS style configuration to another.

How Does CSS Work?

You can use CSS to apply multiple styles on a single HTML document. Those styles can affect the same element once, twice, or many more times over. As these style changes are written into the CSS file, they take a form of precedence from their location. CSS is a rule-based language — you define the rules by specifying groups of styles that should be applied to particular elements or groups of elements on your web page. In the Introduction to HTML module, we covered what HTML is and how it is used to mark up documents. Headings will look larger than regular text, paragraphs break onto a new line and have space between them.

Using CSS

Usually, the rule that’s later in the CSS doc is the winner – unless the first rule is more specific. For example, you may have two rules in your CSS file that conflict – like setting the body font to blue and the paragraph font to green. In this case, the winning rule would be the paragraph font, because it’s more specific than body font. The final coloring and font-size values were taken from the last entry on the stylesheet. The font-family and font-weight properties were added along the way and kept on the final render as well.

You can call a rule with a selector that applies to paragraphs (identified with the ‘p’ tag) and it will affect all paragraphs within your HTML document. CSS was first developed in 1997 as a way for web developers to define the visual appearance of the web pages that they were creating. It was intended to allow web professionals to separate the content and structure of a website’s code from the visual design, something that had not been possible prior to this time. Websites are comprised of a number of individual pieces, including images, text, and various documents. This article will delve into CSS, covering what it is and where it is used on websites today.

This era saw inconsistent CSS support across browsers, leading to the need for complex workarounds to achieve consistent designs. In the early days of the web (late 1980s and early 1990s), websites were primarily plain text with minimal formatting options.
