A website consists of many files: text content, code, stylesheets, media content, and so on. When you're building a website, you need to assemble these files into a sensible structure on your local computer, make sure they can talk to one another, and get all your content looking right, before you eventually upload them to a server. Dealing with Files discusses some issues you should be aware of so you can set up a sensible file structure for your website.
Where should your website live on your computer?
When you are working on a website locally on your own computer, you should keep all the related files in a single folder that mirrors the published website's file structure on the server. This folder can live anywhere you like, but you should put it somewhere where you can easily find it, maybe on your Desktop, in your Home folder, or at the root of your hard drive.
- Choose a place to store your website projects. Here, create a new folder called
web-projects(or similar). This is where all your website projects will live.
- Inside this first folder, create another folder to store your first website in. Call it
test-site(or something more imaginative).
An aside on casing and spacing
You'll notice that throughout this article, we ask you to name folders and files completely in lowercase with no spaces. This is because:
- Many computers, particularly web servers, are case-sensitive. So for example, if you put an image on your website at
test-site/MyImage.jpg, and then in a different file you try to invoke the image as
test-site/myimage.jpg, it may not work.
- Browsers, web servers, and programming languages do not handle spaces consistently. For example, if you use spaces in your filename, some systems may treat the filename as two filenames. Some servers will replace the spaces in your filenames with "%20" (the character code for spaces in URIs), breaking all your links. It's better to separate words with dashes or underscores:
For these reasons, it is best to get into the habit of writing your folder and file names lowercase with no spaces, at least until you know what you're doing. That way you'll bump into fewer problems.
What structure should your website have?
Next, let's look at what structure our test site should have. The most common things we'll have on any website project we create are an index HTML file and folders to contain images, style files, and script files. Let's create these now:
index.html: This file will generally contain your homepage content, that is, the text and images that people see when they first go to your site. Using your text editor, create a new file called
index.htmland save it just inside your
imagesfolder: This folder will contain all the images that you use on your site. Create a folder called
images, inside your
stylesfolder: This folder will contain the CSS code used to style your content (for example, setting text and background colors). Create a folder called
styles, inside your
scripts, inside your
Note: On Windows computers, you might have trouble seeing the file names, because Windows has an annoying option called Hide extensions for known file types turned on by default. Generally you can turn this off by going to Windows Explorer, selecting the Folder options... option, unchecking the Hide extensions for known file types checkbox, then clicking OK.

To make files talk to one another, you have to provide a file path between them — basically a route so one file knows where another one is. To demonstrate this, we will insert a little bit of HTML into our
index.html file, and make it display the image you chose in the article "What will your website look like?"
- Copy the image you chose earlier into your
- Open up your
index.htmlfile, and insert the following code into the file exactly as shown. Don't worry about what it all means for now — we'll look at the structures in more detail later in the series.
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>My test page</title> </head> <body> <img src="" alt="My test image"> </body> </html>
- The line
<img src="" alt="My test image">is the HTML code that inserts an image into the page. We need to tell the HTML where the image is. The image is inside the images directory, which is in the same directory as
index.html. To walk down the file structure from
index.htmlto our image, the file path we'd need is
images/your-image-filename. For example, our image is called
firefox-icon.png, so the file path is
- Insert the file path into your HTML code between the double quote marks of the
- Save your HTML file, then load it in your web browser (double-click the file). You should see your new webpage displaying your image!
Some general rules for file paths:
- To link to a target file in the same directory as the invoking HTML file, just use the filename, e.g.
- To reference a file in a subdirectory, write the directory name in front of the path, plus a forward slash, e.g.
- To link to a target file in the directory above the invoking HTML file, write two dots. So for example, if
index.htmlwas inside a subfolder of
test-site, you could reference
- You can combine these as much as you like, for example
For now, this is about all you need to know.
Note: The Windows file system tends to use backslashes, not forward slashes, e.g.
C:\windows. This doesn't matter — even if you are developing your web site on Windows, you should still use forward slashes in your code.
What else should be done?
That is about it for now. Your folder structure should look something like this:
