In this article, we’ll take a closer look at CSS, a rule-based language that describes how documents presented. It’s one of the cornerstone technologies of the World Wide Web and JavaScript. CSS can help you make HTML markup more concise and more consistent. In addition, it makes it much easier for web developers to manipulate the appearance of documents.
CSS is a rule-based language
CSS is a rule-based language that controls the appearance of HTML elements. Each rule applied to a specific element on a web page. This means that the CSS rules you write will targeted by the browser when the page rendered. CSS can use to make webpages look as beautiful as possible, and the rules you write not limited to just style sheets.
In order to use CSS to enhance your web design, you need to have a working knowledge of HTML. HTML, on the other hand, separates a webpage into its body and heading. However, CSS allows you to manipulate these two elements to make the content look beautiful. As the name suggests, CSS is a rule-based language, so the rules you write are different from HTML.
CSS defines rules and styles with selectors. A selector is a snippet of code that identifies the element you want to style. It also specifies a property, such as color, padding, margin, and background. A property defined with a value, which can be an integer or a string. For example, a property called “color” might defined with the value “red.” A declaration is a set of two or more declarations applied to one selector.
CSS styles follow two rules: inheritance and specificity. Styles can be very broad or extremely specific. When these rules conflict, they cascade downward. This allows the author to make a style that applies to a specific portion of a website. A stylesheet can have several rules, and they can all used together for a variety of purposes.
A CSS rule begins with a selector, which is a key part of the syntax. It then specifies an HTML element, such as a level-one heading. It then follows a declaration block. The declaration block can have three declarations. The first property specifies a color for the text, the second specifies the background color, and the third property sets a solid one-pixel border around the header.
CSS 2.1 originally planned as a Level 2 revision. In 2015, low-priority work on CSS 2.2 began. There is also a CSS3 disambiguation.
It gives developers more control over presentation
CSS allows developers to create websites with a variety of presentation styles. It facilitates the publication of content across multiple presentation formats and can customize for nominal parameters such as user preferences, different web browsers, the type of device used to view the content, and the geographic location of the user. CSS allows developers to customize styling of entire websites through global style sheets, which can edit as needed.
CSS is also useful for presentation of the same page on different media. Traditionally, web pages were not printer-friendly, but CSS allows site owners to create a different look for different media. This saves site visitors the trouble of printing pages from their browser. Instead of getting an image or background color in a printout, they will get a text document without these distractions.
It makes HTML markup cleaner
CSS is an extension of HTML, a markup language, used to stylize design. CSS integrated on top of HTML markup and simplifies coding by eliminating the need to describe each element separately. This also helps to reduce errors in coding and creates a cleaner markup. Another benefit of CSS is the ability to apply multiple styles to the same page, giving you more flexibility and control.
