This module carries on where CSS first steps left off — now you’ve gained familiarity with the language and its syntax, and got some basic experience with using it, it’s time to dive a bit deeper. This module looks at the cascade and inheritance, all the selector types we have available, units, sizing, styling backgrounds and borders, debugging, and lots more.
CSS comment, as the name says, with the help of comments, we can pass the message in our code so the user can easily understand the code. With the help of comments, we can make our source code attractive. Values may be keywords, such as «center» or «inherit», or numerical values, such as 200px (200 pixels), 50vw (50 percent of the viewport width) or 80% (80 percent of the parent element’s width).

CSS files are always created with HTML (Hypertext Markup Language) files. HTML is responsible for the content of a webpage, but by itself, it does not have features that support customization of its appearance. Web pages that do not have CSS customization (such as internet error pages) look bland and uninteresting. Developers who wish to create a visually appealing website will use CSS to customize the appearance of a website to their wish. This ability to customize the visuals of a website is one of the main benefits of CSS.
The style sheet with the highest priority controls the content display. Declarations not set in the highest priority source are passed on to a source of lower priority, such as the user agent style. Each rule or rule-set consists of one or more selectors, and a declaration block. A document is usually a text file structured using a markup language — HTML is the most common markup language, but you may also come across other markup languages such as SVG or XML.

But as you’re developing a web page, and you want to modify a single element, you could use inline CSS.

Additionally, cascading can help create themed designs, which help designers fine-tune aspects of a design without compromising the overall layout. Before CSS, nearly all presentational attributes of HTML documents were contained within the HTML markup. All font colors, background styles, element alignments, borders, and sizes had to be explicitly described, often repeatedly, within the HTML. CSS lets authors move much of that information to another file, the style sheet, resulting in considerably simpler HTML. And additionally, as more and more devices are able to access responsive web pages, different screen sizes and layouts begin to appear. Customizing a website for each device size is costly and increasingly difficult.
Text font styling options in CSS include changing the font’s face, adjusting its size and boldness, managing variants and so on. Font- family, -style, -weight, -size, and -variant are the different font attributes. These ratified specifications are called recommendations because the W3C has no control over the actual implementation of the language. Independent companies and organizations create that software. Cascading Style Sheets, fondly referred to as CSS, is a simple design language intended to simplify the process of making web pages presentable.
A good layout design requires that elements be placed correctly on the web pages. You can read about these placement techniques individually in the following section. web development css cascading The text color of an element is defined by its color parameter. For instance, the body selector’s color attribute specifies the page’s default text color.

CSS2, an evolution of CSS, incorporated media queries to allow developers to specify triggers for certain styles to take effect. For example, it can present a printer-friendly version of the page when requested. CSS3 took this a step further by introducing query capabilities to respond to the dimensions of a viewport or a device, the portrait or landscape orientation of the device and the screen resolution. CSS stands for cascading style sheets and is an element of front-end development responsible for determining the overall styling and layout of a web page.
