It means that you can use new CSS as an enhancement, knowing that no error will occur if it is not understood — the browser will either get the new feature or not. In our Debugging CSS article in the next module we will be using browser DevTools to debug CSS problems, and will learn more about how the browser interprets CSS. Properly implemented CSS can enhance web accessibility by making content more readable and adaptable to various devices.
The concepts of cascading and specificity are crucial for managing complex styles efficiently. Additionally, responsive web design, CSS frameworks, and preprocessors are essential tools that enhance productivity and improve the overall quality of web development projects. Before CSS, nearly all presentational attributes of HTML documents were contained within the HTML markup.
HTML and CSS
This will link the .html file to your style sheet (in this case, mysitestyle.css), and all of the CSS instructions in that file will then apply to your linked .html pages. The coding language that serves as the foundation for all web development? Well, if HTML is the first language you’ll want to learn when you’re interested in building websites, its cousin CSS is a close second coding language to learn. Responsive web design means the CSS uses flexible layouts, images and other techniques to style the page automatically for various screen sizes. For example, headings (h1 elements), sub-headings (h2), sub-sub-headings (h3), etc., are defined structurally using HTML.
The final type, inline CSS, is where the CSS code is applied within the HTML code but is not globally applied to a particular element. Instead, the CSS code is used within the HTML code to alter web development css cascading a single element. A CSS stylesheet will contain many such rules, written one after the other. CSS properties have different allowable values, depending on which property is being specified.
Is Tech Right For You?
📌 PS – If you’d like to learn more about CSS, front end development, or web design, Skillcrush can help you get there! Our Break Into Tech course is a comprehensive program designed to help total beginners in tech start a new and fulfilling career. There are various frameworks available that can be used to style the HTML Elements in an interactive manner. With CSS, the design is separate from the content, making it easier to change the design without affecting the content. Think of it like a set of instructions for your website, telling it how to look and feel.
- One of the goals of CSS is to allow users greater control over presentation.
- CSS is among the core languages of the open web and is standardized across Web browsers according to W3C specifications.
- For example, “background-position,” “border-color,” “border-style,” and “border-width, “and “text-align” are properties and “top,” “red,” “dotted,” “thick,” and “left” are values, respectively.
- It offers flexibility to front-end developers with standard UI components.
- If a website was a house, HTML would be the structure of the house, and CSS would be the paint.
- In addition to HTML, other markup languages support the use of CSS including XHTML, plain XML, SVG, and XUL.
We have learned the basics of CSS, what it is for and how to write simple stylesheets. In this lesson we will take a look at how a browser takes CSS and HTML and turns that into a webpage. Managed by a company called ZURB Foundation, it offers an open-source design, offers a mobile-first approach and is particularly useful for creating large-scale web-based applications. It offers flexibility to front-end developers with standard UI components.

This resizing posed a challenge for CSS developers and caused errors in layout and font placement until the development of responsive web design. 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. The first thing that comes to mind after learning about CSS’s many benefits is to reinstate it in your old website.
While neither HTML or CSS is more complex than the other in terms of syntax, a major difference is that HTML can contain CSS within its code and files, but CSS cannot contain HTML. Both HTML and CSS are mutually containing, however, meaning CSS and HTML share tag names with each other. One of the goals of CSS is to allow users greater control over presentation.
A real DOM representation

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. The modular nature of CSS means that styles can be reused in different parts of a site or even across sites, promoting consistency and efficiency.
In addition, using CSS can help to keep your HTML code clean and organized. If your website has a lot of styling information included in the HTML code, it can be difficult to read and edit. By keeping the styling information in a separate CSS file, it will be much easier to read and edit your HTML code. This works particularly well when you want to use a value that is quite new and not supported everywhere. For example, some older browsers do not support calc() as a value. I might give a fallback width for a box in pixels, then go on to give a width with a calc() value of 100% – 50px.
CSS is used in website builder services and web hosting to make a website look nicer without having to change the actual HTML code. This means that if you want to make a small change to the way your website looks, you can do so without having to edit the HTML code itself. This can save a lot of time, especially if you need to make a lot of small changes. You’ve nearly finished this module — we only have one more thing to do.

The property identifies which aspect of the element you want to style and the value specifies how you want to style the element. If a browser is parsing your rules, and encounters a property or value that it doesn’t understand, it ignores it and moves on to the next declaration. It will do this if you have made an error and misspelled a property or value, or if the property or value is just too new and the browser doesn’t yet support it. Since the only rule available in the CSS has a span selector, the browser sorts the CSS very quickly! It applies that rule to each one of the three s, then paints the final visual representation to the screen.
