Tutorial: About HTML Files

Creating your first web page

You are now ready to create a new web page – that is, an HTML file. Here are the steps:

  1. Start Microsoft Visual Code (VS Code) on your computer. Introduction to HTML
  2. Choose the File | New Text File command. Introduction to HTML VS Code creates a new, empty file in a new tab within your VS Code window.   It suggests the name of Untitled-1 for your new file. Introduction to HTML Let’s give your file a new name and save it as an HTML file.
  3. Choose the File | Save As... command. Introduction to HTML
  4. In the dialog box now displayed, save your file in the 📁 exercises sub-folder of your 📁 websites folder with this name:   page-1.html  
    Introduction to HTML

    DO NOT name your web page with an upper-case ‘P’ as in Page-1.html.

    And DO NOT use some other combination of upper and lower-case letters, such as PAGE-1.HTML or page-1.HTML.

    Also, DO NOT enter any blank spaces in the name of your file: type page-1.html NOT page - 1.html or page -1.html.

    Introduction to HTML Because you have included the file name extension (.html), you can ignore the second box named Save as type.   After typing the name of your file, click the Save button.   Notice how VS Code now displays the name of your page-1.html file at the top of the screen. Introduction to HTML

✅  That’s it. You have successfully created your first sample web page.

Your folder and file structure should look as shown below.

Introduction to HTML

Adding the <head> and <body> structure

After creating and naming your new, empty page-1.html web page, your next task is to add the basic <head> and <body> structure to it.

Visual Studio Code offers a convenient shortcut for doing this.

  1. In VS Code, click anywhere in your empty web page and type the exclamation mark ! (Shift key and number 1 key). Introduction to HTML After one or a few seconds, the Emmet Abbreviation menu appears. Click on the first option from the menu. Or press either the Tab or Enter key. Introduction to HTML VS Code now fills your new file with the basic HTML structure. Introduction to HTML
    NOTE: The exclamation mark ! shortcut key is part of Emmet, a collection time-saving tools for web designers and developers that is pre-installed in VS Code.
  2. To make your web page easier to read and edit, add some blank lines after the closing </head> tag and before the opening <body> tag.   Click just before the <body> tag and press the Enter key one, two or three times. Introduction to HTML When you look at the HTML of your web page on the VS Code screen, you can now see visually ‘at a glance‘ where the <head> ends and the <body> begins. Introduction to HTML
  3. Save your HTML file. You can choose the File | Save command from the menu. Or simply press the Ctrl key (Windows) or key (Apple) and press the s (for Save) key.

✅  Well done. You have now created what is called a ‘valid’ web page.

Adding a title to the <head> of your web page

Now you will give a title to your web page.

  1. In the <head> of your page-1.html file, you can see that VS Code has given your page a default title of Document.   This text is located between the opening <title> and closing </title> tags.
     <title>Document</title>
    
  2. Replace this with the following new text:
     <title>A Tale of Two Cities</title>
    
  3. When finished, save your HTML file.

Adding a description to the <head> of your web page

Now you will add a summary description of the contents of your web page.

  1. In the <head> of your web page, at the end of the line that contains the <title> ... </title> tag pair, click with the mouse and then press the Enter key to open a new, blank line. Introduction to HTML Your web page should now look as shown below. Introduction to HTML
  2. Copy the following line:
    <meta name="description" content="A basic web page containing some text from A Tale of Two Cities, a novel published in 1859 by English author Charles Dickens.">
    
  3. Paste the copied text in your web page, on the new, blank line you created under the <title> tag.   See below. Introduction to HTML
  4. Save your page-1.html file.

✅   You are now finished working with the <head> of your first sample web page.

Displaying your web page

Let’s display your page-1.html web page in a web browser.

  1. Open File Explorer (Windows) or Finder (Apple Mac), and display the contents of your 📁 websites/exercises sub-folder.   Your choice of default web browser determines which icon is shown for your HTML files.
    • If you have set Google Chrome as your default web browser, your screen should look as shown below. Introduction to HTML
    • If you have set Mozilla Firefox Developer Edition as your default web browser, your screen shown look as below. Introduction to HTML
    In either case, double-click the page-1.html file to open it.
  2. If some other web browser is your default:
    • Right-click the page-1.html file.
    • From the context menu displayed, choose Open with.
    • Select either Firefox Developer Edition or Google Chrome to open the web page. file-explorer-right-click
  3. Your web page should look as shown below. Introduction to HTML Note the address of your web page in the Address Bar of your web browser.
    • The first part of the address shows the name of the folder and sub-folder (websites/exercises) that contains your web page.
    • The second part of the address shows the name of the file (page-1.html).
    Also in the Address Bar of the web browser you can see that the forward slash / character is used to separate the name of the file from the name of the folders where the file is located.
  4. Because you have not yet added any content to the <body> of your web page, it looks as if it is empty.   However, your web page does contain the correct content within its <head>.   To view this:
    • Right-click anywhere on the web page.
    • From the context menu displayed, choose the View page source command. Introduction to HTML
  5. Your web browser opens a new tab and displays the HTML source code of your web page. Introduction to HTML

Adding text to the <body> of your web page

In this section, you will copy-and-paste some text content to the <body> of your web page.

  1. Drag down and across all the text in the grey box below to select it.

    A Tale of Two Cities

    It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair.

    We had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way - in short, the period was so far like the present period, that some of its noisiest authorities insisted on its being received, for good or for evil, in the superlative degree of comparison only.

    Small Heading
    There were a king with a large jaw and a queen with a plain face, on the throne of England; there were a king with a large jaw and a queen with a fair face, on the throne of France. In both countries it was clearer than crystal to the lords of the State preserves of loaves and fishes, that things in general were settled for ever.

    Small Heading
    All these things, and a thousand like them, came to pass in and close upon the dear old year one thousand seven hundred and seventy-five. Environed by them, while the Woodman and the Farmer worked unheeded, those two of the large jaws, and those other two of the plain and the fair faces, trod with stir enough, and carried their divine rights with a high hand.

    Smaller Heading
    A wonderful fact to reflect upon, that every human creature is constituted to be that profound secret and mystery to every other. A solemn consideration, when I enter a great city by night, that every one of those darkly clustered houses encloses its own secret; that every room in every one of them encloses its own secret; that every beating heart in the hundreds of thousands of breasts there, is, in some of its imaginings, a secret to the heart nearest it!

    by Charles Dickens, published by Chapman and Hall in 1859.

  2. Right-click on the selected text and, from the context menu, choose Copy. Introduction to HTML
  3. In VS Code, with the page-1.html file open, click on the first blank line after the opening <body> tag. Introduction to HTML Now, paste the copied text.
  4. VS Code may add one or more blank lines after the opening <body> tag and before the pasted text. You can delete these blank lines. Introduction to HTML
  5. Save your file and then display it in your web browser.

As you can see, the web browser ignores any paragraph breaks in the file and displays all the text content as a single block.

Introduction to HTML

This is because the content is not marked up with HTML tags.

Marking up the content in your web page

Now you will mark-up the text of your web page with opening and closing pairs of the following HTML tags: <h1>, <h2>, <h3> and <p>.

The < symbol is known as the left angle bracket. And the > symbol is known as the right angle bracket.

  • To type a left angle bracket, hold down the Shift key and type the , (comma) key.
  • To type a right angle bracket, hold down the Shift key and type the . (full stop) key.
  • The / symbol is called the forward slash. The key is just to the right of the . (full stop).
Introduction to HTML
  1. Wrap the main heading text “A Tale of Two Cities” within <h1> ... </h1> tags.
  2. Wrap the two “Small Heading” texts within <h2> ... </h2> tags.
  3. Wrap the “Smaller Heading” text within <h3> ... </h3> tags.
  4. Wrap the remaining paragraphs of text with <p> ... </p> tags.
  5. On the last line, wrap the words “Charles Dickens” within italics <i> ... </i> tags.
  6. And wrap the words “Chapman and Hall” within bold <b> ... </b> tags.
  7. The body of your HTML file should now look as shown below. Introduction to HTML
  8. Save your page-1.html web page file.
  9. Display your web page in your web browser. It should now look as shown below. Introduction to HTML

✅  You have now finished working with your first sample web page.

Creating a home page for your website

In this section, you will use your sample web page named page-1.html as the basis for creating a front or ‘home’ page named index.html for your website.

  1. In VS Code, with the page-1.html file open, choose the File | Save As... command, and save your web page in your ‘main’ 📁 websites folder this new name:   index.html Introduction to HTML  
    Introduction to HTML

    DO NOT name your web page with an upper-case ‘I’ as in Index.html.

    And DO NOT use some other mixture of upper and lower-case letters, such as INDEX.HTML or index.HTML or whatever.

    Also, DO NOT enter any blank spaces in the name of your file: type index.html NOT index .html

    Your folder and file structure should look as shown below. Introduction to HTML
  2. In the <head> of your new index.html file, update the title and the description tags by copying and pasting the lines below to replace the old title and description tags and content.
    <title>Mary Smith | Home Page</title>
    <meta name="description" content="Welcome to my website that showcases some of my digital creations.">
    
    Replace the name “Mary Smith” with your own name. And edit the text as you wish. The <head> of your web page should look similar to the sample below. Introduction to HTML
  3. Delete all the content from inside the <body> ... </body> tags of the web page. Introduction to HTML
  4. Copy-and-paste the new content below.
    <h1>Welcome</h1>
    <h2>Mary Smith</h2>
    
    <h3>Sample Web Pages</h3>
    
    <p><a href="exercises/page-1.html">A Tale of Two Cities</a></p>
    
  5. Save your web page and view it in your web browser. It should look like that below. Introduction to HTML
  6. Click on the hyperlink to ensure it works correctly.

✅  You have now finished working with your home web page.

Adding a back link to your sample page

As a final task, let’s add a hyperlink to your sample web page that, when clicked, brings the user back to your home web page.

  1. In VS Code, open the page-1.html sample web page you created earlier in your 📁 websites/exercises sub-folder:
  2. At the end of the file, just before the closing </body> tag, copy-and-paste the following line.
    <p><a href="../index.html">Back to Home page</a></p>
    
    Introduction to HTML
  3. When finished, save your sample web page.
  4. In your web browser, display the sample web page and verify the “Back to Home page” hyperlink works correctly. Introduction to HTML


✅  Task completed.

You will learn more about hyperlinks in HTML in later Tutorials.

Adding comments to HTML code

In a web page, a comment is one or more lines of text that are visible only in the source code – but are not actually displayed in the web browser.

You can see an example of a short, one-line comment below.

  <!-- This is a comment -->

And here is an example of a longer, multi-line comment.

Follow these steps to create a comment in VS Code.

  • Type a left angle bracket (<), an exclamation mark (!) and two dashes (--).   The is the opening part of the comment tag.
  • VS Code automatically adds the closing part of the comment tag: two dashes (--) and a right angle bracket (>). Introduction to HTML
  • Click in the middle of the four dashes and press the Spacebar a few times. Introduction to HTML
  • Type your comment in the blank spaces. Introduction to HTML

By default, VS Code displays comments in a dark green colour.

Uploading your web pages to GitHub

Your final task is to upload your two web pages to your account on GitHub.

  1. Open a new tab in your web browser and go to GitHub.com. If you are not already signed in to your GitHub account, sign in now. github-signin
  2. On your GitHub home page, click the name of the repository (‘repo’) that holds your web pages. Its name will look as follows, where username is your chosen username on GitHub.   username.github.io github-signin
  3. On the next GitHub screen displayed, near the right of the screen, you can see a button named Add file. Click on it. github-upload-portfolio
  4. From the dropdown list displayed, choose the option Upload files. Project Animation Google Fonts
  5. In File Explorer (Windows) or Finder (Apple Mac), drag-and-drop your index.html file and your 📁 exercises sub-folder to upload them to your repository on GitHub. Introduction to HTML
  6. Scroll down to the bottom of the GitHub screen, and accept or edit the short message (Add files via upload) in the Commit changes box.
  7. Finally, click the green Commit changes button to upload your files. Project Animation Google Fonts

Your web pages are now published on GitHub at web addresses similar to the following, where username is the username you have chosen for your GitHub account:

https://username.github.io/index.html
– or simply –
https://username.github.io
https://username.github.io/exercises/page-1.html

It may take a few minutes for your uploaded files to appear on GitHub.
