Tags like were introduced in HTML version 3.2, and it caused quite a lot of trouble for web developers. Due to the fact that web pages have different fonts, colored backgrounds, and multiple styles, it was a long, painful, and expensive process to rewrite the code. Thus, CSS was created by W3C to solve this problem. CSS styling text With the basics of the CSS language covered, the next CSS topic for you to concentrate on is styling text — one of the most common things you’ll do with CSS. Here we look at text styling fundamentals, including setting font, boldness, italics, line and letter spacing, drop shadows, and other text features. We round off the module by looking at applying custom fonts to your page, and styling lists and links.

How does CSS work

You can add JavaScript to an HTML document by adding these “scripts,” or snippets of JavaScript code, into your document’s header or body. This selector will select any element that is inside an . So in your example document, you should find that the in the third list item is now purple, but the one inside the paragraph is unchanged. The “Browser support information” section in the “What is CSS” article mentioned that browsers do not necessarily implement new CSS features at the same time. In addition, many people are not using the latest version of a browser. When a browser displays a document, it must combine the document’s content with its style information.

tags on a page, while the declaration could be “font-size: 24px.” This would make all

The browser gathers HTML resources (embedded images, videos, etc.) and linked CSS. Table-cell These elements behave like HTML elements. List-item can also be combined with any keyword and the flow or flow-root keywords. This is a perfect representation of my big “AHA” moment with CSS. Odd as it may seem, realizing that “selector” actually meant that you are “selecting” something was a huge step for me in understanding how CSS worked.

Add the link to the location of your CSS in the directory. If you want to have more than one CSS file for keeping your code more organized, put your CSS files in a folder called Styles. Since CSS files are just text files, all you need is a text editor to start writing CSS. Different versions of CSS are still used all the time, sometimes making it confusing for beginners to learn the language. Due to only requiring a few lines of code for making changes to many pages at once, the website database remains uncluttered and websites load faster.

Descendant selectors allow you to add these special styles to specific words without affecting the surrounding text or changing your HTML document. If they do, you can use pseudo-classes to capture temporary user https://www.globalcloudteam.com/ information such as when they hover, click, and follow the link. A CSS class is an attribute used to define a group of HTML elements in order to apply unique styling and formatting to those elements with CSS.

Say you want to remove the underline from only certain links in all states. Meaning, no matter if the user has visited the link, is hovering over it, or is actively pressing down on it, an underline will not appear below these specific links. Pseudo-classes are identified by a colon followed by the class.

How does understanding the cascade help me write better CSS?

This has different states depending on whether it is unvisited, visited, being hovered over, focused via the keyboard, or in the process of being clicked . You can use CSS to target these different states — the CSS below styles unvisited links pink and visited links green. The live example below includes the two rules above. Try adding a rule to make a span red if it is inside a paragraph. You will know if you have it right because the span in the first paragraph will be red, but the one in the first list item will not change color. When tags like , and color attributes were added to the HTML 3.2 specification, it started a nightmare for web developers.

How does CSS work

But how does the cascade actually resolve conflicts? By looking at the importance, specificity, and source order of conflicting declarations in order to determine which one takes precedence. It’s important to understand the difference between HTML and CSS because they are two very different languages that serve two very different purposes. A well-designed website will use both HTML and CSS code to create a site that is both informative and visually appealing. 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.

Selecting multiple elements

This will cause the element itself to no longer be announced by screen reading technology. This is incorrect behavior according to the CSS specification. CSS 2 used a single-keyword, precomposed syntax for the display property, requiring separate keywords for block-level and inline-level variants of the same layout mode.

The first post in this series was a deep dive into how the browser actually renders CSS to pixels. In this second post, we’ll dive into an often-misunderstood feature of the CSS language — the cascade. Now that you have some understanding of what CSS is, let’s move on to Getting started with CSS, where you can start to write some CSS yourself. CSS is no different — it is developed by a group within the W3C called the CSS Working Group. This group is made of representatives of browser vendors and other companies who have an interest in CSS. There are also other people, known as invited experts, who act as independent voices; they are not linked to a member organization.

The CSS display property is specified using keyword values. Very useful information for the persons who are learning CSS. I wouldn’t like to rely on this selector, it’s too invisible when working on the html and an extra newline is easily added.

  • Important, which over time can make your CSS more brittle.
  • For example, ID selectors are more specific than class selectors, and class selectors are more specific than type selectors.
  • Cascade combines the CSS declarations coming from all these different sources.
  • This saves time, shortens the code, and makes it not as prone to errors.
  • (In this example, color is a property of the elements.) In CSS, you choose which properties you want to affect in the rule.
  • Each one has its own rules and syntax that need to be learned step by step.

Some layout models such as table and ruby have a complex internal structure, with several different roles that their children and descendants can fill. This section defines those “internal” css web development display values, which only have meaning within that particular layout mode. Grid The element behaves like a block-level element and lays out its content according to the grid model.

Once you understand the fundamentals of HTML, we recommend that you learn further HTML and CSS at the same time, moving back and forth between the two topics. This is because HTML is far more interesting and much more fun to learn when you apply CSS, and you can’t learn CSS without knowing HTML. Finally, using CSS can make it easy to change the look of your entire website by changing just one file.
