Presenting a document to a user means converting it into a form usable by your audience. Browsers , like Firefox , Chrome , or Edge , are designed to present documents visually, for example, on a computer screen, projector or printer. Note: A browser is sometimes called a user agent , which basically means a computer program that represents a person inside a computer system. Browsers are the main type of user agent we think of when talking about CSS, however, it is not the only one.
CSS can be used for very basic document text styling — for example changing the color and size of headings and links. It can be used to create layout — for example turning a single column of text into a layout with a main content area and a sidebar for related information.
It can even be used for effects such as animation. Have a look at the links in this paragraph for specific examples. CSS is a rule-based language — you define rules specifying groups of styles that should be applied to particular elements or groups of elements on your web page. For example "I want the main heading on my page to be shown as large red text.
The rule opens with a selector. This selects the HTML element that we are going to style. Inside those will be one or more declarations , which take the form of property and value pairs. Each pair specifies a property of the element s we are selecting, then a value that we'd like to give the property. Before the colon, we have the property, and after the colon, the value. Our CSS learning area contains a wealth of tutorials to take you from beginner level to proficiency, covering all the fundamentals.
We have put together a course that includes all the essential information you need to work towards your goal. CSS Cascading Style Sheets is used to style and layout web pages — for example, to alter the font, color, size, and spacing of your content, split it into multiple columns, or add animations and other decorative features. This module provides a gentle beginning to your path towards CSS mastery with the basics of how it works, what the syntax looks like, and how you can start using it to add styling to HTML.
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. The aim here is to provide you with a toolkit for writing competent CSS and help you understand all the essential theory, before moving on to more specific disciplines like text styling and CSS layout.
These three programming languages have survived through the years and have become the pillars for the new emerging technologies. With knowledge of CSS3, we can pursue our career in many fields, including mobile application development and IoT Apps development.
For creating interactive and responsive web pages, we would require Bootstrap knowledge, which is a CSS framework, thereby requiring us to be proficient in CSS.
Thus, there are plenty of paths that can be taken after acquiring skills in CSS3. CSS3 is a powerful tool for Web designers. Since CSS3 has been introduced, there has been better control over the demonstration of content on a website. No matter where we decide to use our programming abilities, it will be seen that web technologies are truly foundational and necessary to get the most out of every platform.
