Everything You Need to Know About CSS
Blog Introduction: When it comes to web design, CSS is one of the most important languages you need to learn. CSS, or Cascading Style Sheets, is a style sheet language used for describing the presentation of a document written in a markup language. In other words, CSS is what tells your web page how to look.
CSS handles everything from font size and color to spacing and layout. If you want to create a website that looks professional and polished, then you need to learn CSS. In this blog post, we’ll give you a crash course in everything you need to know about CSS. By the end, you’ll have a better understanding of how CSS works and be able to start styling your own web pages.
CSS Basics
Before we dive into all the different things CSS can do, let’s start with the basics. As we mentioned before, CSS is a style sheet language used for describing the presentation of a document written in a markup language. In order to use CSS on your web page, you’ll need to create a separate CSS file or include it inline within your HTML document.
Once you have your CSS file set up, you can start adding styles to your web page. Styles are typically added as rules. A rule consists of a selector and a declaration. The selector points to the HTML element you want to style and the declaration tells the browser how that element should be styled. For example, say you want all the paragraphs on your web page to be blue. Your CSS rule would look like this:
p {
color: blue;
}
In this case, “p” is the selector (it points to all paragraph elements) and “color: blue” is the declaration (it tells the browser to make all paragraphs blue). The declaration always goes inside curly braces {}. One rule can have multiple declarations; just make sure each declaration is on its own line and ends with a semicolon ;. For example, if we wanted all paragraphs on our web page to be blue and have 16px of margin on the left and right sides, our rule would look like this:
p {
color: blue;
margin-left: 16px;
margin-right: 16px;
}
And that’s really all there is to it! Now let’s take a look at some of the different things we can do with CSS…
Which Elements Can I Style?
Almost any element on an HTML page can be styled with CSS. That includes everything from headers (h1) and paragraphs (p) to links (a) and list items (li). In addition to styling individual elements, you can also style entire sections of your web page by using class or id selectors. We won’t get into too much detail about those here but just know that they give you even more control over how your web page looks. Trust us, once you start playing around with CSS, you’ll be surprised at just how much control you have over the look of your web page!
What Can I Do With CSS?
Now that we’ve covered the basics of how CSS works, let’s take a look at some of the different things we can do with it. As we mentioned before, CSS gives us complete control over typography—we can change fonts, font sizes, colors, line heights, letter spacing… pretty much anything related to text! In addition to typography, we can also use CSS for layouts—we can control where elements are positioned on our web pages and how they’re sized and spaced out. And if that wasn’t enough already, we can also use CSS3 properties for things like animations and adding filters/effects (like blurring or grayscale) without having to rely on heavy image files. No matter what kind of website you’re trying to create, chances are good thatCSS will play a role in its design!
As you can see, learning CSS is well worth your time and effort! Not only does it give you complete control over the design of your website but it also helps reduce loading times by keeping image files small (since most styling effects can be achieved using code).
