In this tutorial, you will set up the folders and files necessary for exploring CSS and building a website. Using a code editor, you will create a project directory for our website, a folder and file for our CSS code, a file for our HTML code, and a folder for images. This tutorial series uses Visual Studio Code, a code editor freely-available for Mac, Windows, or Linux, but you may use whichever code editor you prefer. Note that certain instructions may need to be slightly modified if you use a different editor.
How To Create HTML and CSS Files and Folders
After opening your preferred text editor, open up a new project folder and name it
css-practice. You’ll use this folder to store all of the files and folders you create in the course of this tutorial series.
To create a new project folder in Visual Studio Code, navigate to the “File” menu item in the top menu and select “Add Folder to Workspace.” In the new window, click the “New Folder” button and create a new folder called
Next, create a new folder inside
css-practice and name it
css. Inside this folder, open up a new file in your project directory and save it as
styles.css—this is the file you’ll use to store our CSS style rules. If you are using Visual Studio Code, you can create a new folder by using
Right Click(on Windows) or
CTRL + Left Click (on Mac) on the
css-practice folder, selecting “New Folder” and creating the
css folder. Then, click
Right Click(on Windows) or
CTRL + Left Click (on Mac) on the new
css folder, select “New File”, and create the file
styles.css as illustrated in the gif below:
Save the file and leave it open.
You also need to create a file to add our HTML content—the text, images, and HTML elements that will be rendered in the browser. In the project directory
css-practice, open an additional new file and save it as
index.html in the same way you created the
styles.css file above. Make sure to save this
index.html file in the
css-practice folder and not in the
Next, you need to add a line of code in the
index.html document that instructs the browser to use the
styles.css file as our style sheet. To do this, you’ll use the HTML
<link> tag and link to the
styles.css file. Add the following code snippet to your HTML document:
<link rel="stylesheet" href="css/styles.css">
This code snippet tells the browser to interpret the HTML code according to the stylesheet located at
css/styles.css. Make sure you don’t erase this line while adding or deleting content to your
index.html file throughout this tutorial series. Save your
index.html file and keep it open.
Finally, create an additional folder inside
css-practice and name it
images in the same way that you created the
css folder above. This folder will be where you save any images you use in this tutorial series.
You should now have a project folder named
css-practice that contains the folders and files necessary for exploring CSS in this tutorial series:
- A folder named
cssthat contains the file
- An empty folder named
- A file named
If you are using Visual Studio Code, your editor should now display the following file tree and the open files:
Notice that the file names include extensions (
.css) that refer to the type of content they contain. You will add content to these files in our hands-on exercises in the tutorials that follow.
Debugging and Troubleshooting CSS and HTML
Precision is important when working with HTML and CSS. Even an extra space or mistyped character can keep your code from working as expected.
If your HTML or CSS code is not rendering in the browser as intended, make sure you have written the code exactly as written in the tutorial. Though we encourage you to manually write out the code for the purpose of learning, copy and pasting can be helpful at times to ensure that your code matches the examples.
HTML and CSS errors can be caused by a number of things. Check your markup and CSS rules for extra or missing spaces, missing or misspelled tags, and missing or incorrect punctuation or characters. You should also make sure that you don’t accidentally use “curly” or “smart” quotation marks like
" that are often used by word processors. Curly quotes are designed for human-readable text and will cause an error in your code as they are not recognized as quotation marks by browsers. By typing quotation marks directly into your code editor, you can make sure you are using the right kind.
Also, each time you change your code, make sure to save your file before reloading it in the browser to check your results.
A Quick Note on Automatic HTML Support Features
Some code editors—such as the Visual Studio Code editor we’re using in this series—provide automatic support for writing HTML code. For Visual Studio Code, that support includes smart suggestions and auto completions. While this support is often useful, be aware that you might generate extra code that will create errors if you’re not used to working with these support features. If you find these features distracting, you can turn them off in the code editor’s preferences.
You are now ready to proceed with the tutorial series. In the next tutorial, you’ll begin exploring how CSS rules are used to control the style and layout of HTML content on a webpage.
