Hey there! Can you believe how much the internet has evolved since its early days? One of the most noticeable changes? How amazing it looks now!
Seriously, websites these days look so slick and polished that it’s easy to forget what they’re really made of — just a bunch of files storing text and media content. It’s kind of like the magic trick of modern web design: making us forget about the nuts and bolts and just enjoy the ride. And we have CSS to thank for that!
Once you’ve got HTML down, CSS is the next big language to learn if you want to create awesome online experiences. See, with all the cool advancements in front-end web design lately, users have come to expect a lot more from the websites they visit. If a site doesn’t meet our visual standards, it can really put a damper on our experience. Best-case scenario, we just think the folks behind the website aren’t up to snuff. Worst-case scenario? We’re outta there, never to return.
So, if content is king, CSS is definitely the trusty sidekick. That’s why any website owner or savvy marketer should at least have a grasp of the basics. After all, it’s what helps turn a plain ol’ website into something truly special!
In this complete guide, you’ll get all the essentials you need to start exploring and creating with CSS, covering:
- What is CSS?
- The difference between HTML and CSS
- How to write CSS code
- How to link CSS code to your HTML documents
- The important concepts of cascade, specificity, and inheritance
Before we dive in further, it’s important to have a good grasp of HTML basics. We’ll be chatting a lot about elements, tags, classes, and IDs, so make sure you’re familiar with them!
What is CSS?
CSS stands for Cascading Style Sheets. It’s a language specifically designed to style and format the appearance of your webpages. Imagine HTML as the skeleton of your webpage, providing structure and content, while CSS acts like the muscles and skin, defining how it looks and feels.
Key Points
- CSS separates presentation from the structure of a Web page.
- It enhances the web by changing the look and feel of Web pages.
- CSS can be applied to HTML elements using three methods: inline, internal, or external.
The difference between HTML and CSS
- HTML (HyperText Markup Language): Defines the content and structure of a webpage using tags. It tells the browser what elements are on the page (headings, paragraphs, images, etc.) but not how they should look.
- CSS: Takes control of the visual presentation. It defines things like fonts, colors, layout, spacing, and more.
How to write CSS code
CSS code is written using selectors and properties.
- Selectors: Target specific HTML elements you want to style. There are different types of selectors, like element tags (e.g.,
h1), class names (e.g.,.important), or IDs (e.g.,#banner). - Properties: Define the styles you want to apply. These include font properties (size, family, color), background properties (color, image), margins, padding, and many more.
Here’s a basic example:
In this example:
h1is the selector targeting all<h1>elements.colorandfont-sizeare properties.blueand2emare the corresponding values.
How to link CSS code to your HTML documents
There are three ways to link your CSS code to your HTML document:
- Internal CSS: Defined directly within the
<head>section of your HTML using a<style>tag. Good for small styling needs specific to that page.
- External CSS: Written in a separate CSS file (.css extension) and linked to your HTML using a
<link>tag in the<head>section. Ideal for styles you want to apply to multiple pages.
- Inline CSS: Added directly to an HTML element using the
styleattribute. Use sparingly as it can make code messy.
The important concepts of cascade, specificity, and inheritance
Cascade:
Determines which CSS rules apply when multiple rules match the same element. The cascade follows three main principles:
- Importance: Styles marked with
!importanthave the highest priority. - Specificity: More specific selectors have higher priority.
- Source Order: When selectors have equal specificity, the last one defined overrides the others.
Specificity:
A measure of how specific a CSS selector is. Specificity is calculated based on the types of selectors used:
- Inline styles (highest specificity)
- IDs (
#id) - Classes, attributes, and pseudo-classes (
.class) - Elements and pseudo-elements (
element)
- The paragraph will be red because the ID selector has higher specificity.
Inheritance:
Determines whether a property value is inherited from its parent element. Many CSS properties, such as color and font-family, are inherited by default, while others, like margin and padding, are not.
Example:
- The paragraph text will inherit the
colorfrom thebodybut will use its ownfont-size.
By understanding these concepts, you can write effective and maintainable CSS code to create beautiful and functional web pages.
