Key Concepts in HTML: Building the Structure of Web Pages

In the world of making websites, HTML is super important. It’s like the skeleton of every webpage you see on the internet. Imagine it as the blueprint that tells your browser how to show everything on a webpage, from text to images to buttons. Understanding the basic ideas of HTML is like learning the ABCs of web design. This article is here to guide you through these simple but essential concepts, so you can start creating your own awesome web pages with confidence.

How To Start With It?

We have jotted down this step-by-step guide, keep reading and experimenting!

Exploring HTML Code

Ever wondered how websites are built? HTML is the magic behind every webpage you visit. To peek behind the curtain and see the code that makes up a webpage, it’s as simple as a right-click. Just visit any webpage, right-click, and select “view page source”. Or, if you prefer shortcuts, hit CTRL + U (or CMD + U for Mac users) to instantly inspect the source code.

Understanding HTML Building Blocks: The Elements

HTML documents are like building blocks, made up of elements that structure the content you see on a webpage. Each element comes with an opening tag, a closing tag, and the content sandwiched between them. These elements tell the browser how to display different parts of the webpage, like headings, images, paragraphs, and more. For instance, the <em> element tells the browser to emphasise the enclosed text.

Inline and Block Elements

HTML is full of elements, each with its role to play. Block-level elements, like <p>, <div>, and <table>, always start on a new line and stretch the full width of the screen. Meanwhile, inline-level elements only take up the necessary space and don’t force a new line.

HTML Element Nesting

In HTML, nesting is like stacking building blocks. It’s the practice of placing one HTML element inside another. This technique not only organises your code but also enhances its readability for you and other developers. Witness the beauty of HTML nesting in action as elements snugly fit within others, creating a well-structured hierarchy.

Mastering CSS: Creating Rules with Ease

CSS rules, also termed rulesets, combine various CSS properties to modify the appearance of HTML elements. They consist of a CSS selector and properties, dictating the styling for targeted elements. In a specific example, a CSS rule is crafted to style the div element, specifying properties like border colour and font size. This rule determines the visual presentation of the div element on a webpage.

–        Setting Multiple Styles in a CSS Rule

In this part, you’ll discover how to set values for multiple properties within a CSS rule. This technique is handy because it enables you to assign various styling instructions to an HTML element simultaneously. To put it simply, if you wish to apply border colour, font size, and other styles to a <div> tag, you can achieve that in one go.

–        Making Pictures Look Good with CSS

In this part, we’ll learn how to make pictures look good with CSS. We’ll do things like add borders, change sizes, and make our pictures special on our webpage. First, put a picture on your webpage. The CSS we’ll use will change all the pictures on the page.

–        Styling Classes with CSS

Now, let’s learn about creating classes using CSS. Here, we’ll understand how to apply CSS rules specifically to HTML elements with certain classes. First, let’s create an HTML element with a class, and then we’ll apply CSS to the entire class. By applying CSS to the whole class, we can style all elements with that specific class.

In this example, we have three different elements all sharing the same class. When we apply CSS to the class, it will affect all elements in that class.

To use the class as a selector in CSS, we put a ‘.’ symbol before writing the class name in the CSS file.

–        Making Styling IDs Unique with CSS

When creating CSS rules, using IDs as selectors is akin to using classes, but IDs are unique in the HTML document. Unlike classes, no two elements can share the same ID. IDs are typically assigned to elements that appear only once in the HTML document, like the navbar or logo.

–        Using Pseudo-classes in CSS

Pseudo-classes are special classes triggered by certain actions or states specified in the selector. For instance, the: hover pseudo-class changes the appearance of an element when a user hovers over it with their mouse.

For example, if we hover over the image mentioned earlier, the border colour of the image changes.

–        Making <div> Elements Look Nice with CSS

The <div> tag is commonly used to define containers for HTML elements, helping organise the layout of a webpage. Now, let’s explore how to style the <div> element and its children elements.

Easy CSS Tricks: Adjusting Content, Padding, Borders, and Margins

Before delving into adjusting the content, padding, borders, and margins of an HTML element, it’s essential to grasp the CSS box model. This model is like a box wrapping around each HTML element in the webpage.

  • The Content Box: This is where the actual content of the HTML element appears, like images and text.
  • Padding: It’s the transparent space around the content of the element.
  • Border: This box surrounds the padding area. Initially, the border value for HTML elements is zero, but increasing it adds space between the padding and margin box.
  • Margin: It’s the transparent space outside the border box.

Let’s use the example of the previous image to understand how to adjust these values.

Simple Steps to Build Your Website with HTML and CSS

Many people wonder if it’s possible to do custom web development in London using just HTML and CSS. Surprisingly, it is indeed possible and can result in a visually appealing website. HTML, which stands for Hypertext Markup Language, provides the structure or skeleton of the website, while CSS (Cascading Style Sheets) adds visual flair to it. Let’s break down the process into seven simple steps:

Step 1: Sketch the Layout

Start by sketching out a basic structure of your website. Even simple drawings can help. There are also online tools available to assist you in designing your website layout.

Step 2: Set up the Basic HTML Structure

Create a new folder for your project and add an empty index.html file inside it. Write the basic HTML boilerplate code within this file. Add some placeholder content to test if the code runs properly in a browser.

Step 3: Create Major Layout Elements

In the HTML file, define the major sections of your layout using <section> elements.

Step 4: Fill in HTML Content

Now, fill in the content for each section. For now, use dummy text to represent the actual content.

Step 5: Apply Basic CSS for Layout

In the linked CSS file, add basic styling to make your webpage resemble the layout you sketched. Focus on adjusting the height, width, padding, margin, and display properties of sections and images.

Step 6: Style Individual Elements

Now, apply specific styles to individual elements such as fonts, borders, and colours to enhance the appearance of your content.

Step 7: Add Background colours and Images

Finally, add background colours and images to sections to add visual appeal and make your website more attractive.

Once you’ve completed all these steps, your website should be ready to go. Remember, you can always add more CSS to further enhance its appearance.

Conclusion

Building a website with just HTML and CSS is not only possible but can yield impressive results. By following the simple steps outlined above, you can create a visually appealing and functional website from scratch.
