Guide to HTML, CSS and JavsScript (Buffalo State College Version)
Chapter 1: Servers, Clients, and File Storage
When you use your browser to visit a web page your browser sends a request out via the internet to find the machine that web page is hosted on. That machine is known as a "web server" (*server*). The machine you are sending the request from is known as the *client*. The web server is available 24x7 and makes your files available via the internet. The files on your local machine (*client*) cannot be accessed by anyone via the internet. The web server has some disk space allocated for the files that it uses to send back to the browser. The browser is responsible for rendering (displaying) the web page based on the files (text, images, media, etc.) it receives from the web server.
So, you need a web server where you can upload your files so they can be displayed when someone visits your web site. If you are a student then, most likely, your school provides you with a small amount of disk space on their web servers. If you need to create a site that is not school related, then you need to either rent space from a web hosting company or use one of the many free web site providers.
Since this textbook is directed towards students, I'm going to use the Buffalo State College web servers in my examples.
There are many ways to connect to a web server so you can manage your files. Check with your school for information about using their web server and downloading any necessary software. You could use any of these methods: SSH/vim/SFTP, edit/SFTP.
One way to manage your web site files is to connect to your web server via a secure telnet connection (known as an SSH client). If you are using a Windows machine I recommend using putty and for a Mac I recommend using the "
Terminal (ssh)" application. You need to know some connection settings for your SSH client. Using the
bscacad3.buffalostate.edu server as an example, here are the necessary settings:
After logging in to your account you can use the Unix shell commands to manage your files.
Your files are stored in a directory (folder) which is setup and named a certain way so that the web server can find your files when someone enters your URL in their browser address window or clicks a link that goes to your web page. For my examples that directory is called *
public_html*. Again, using
bscacad3.buffalostate.edu as an example, the URL of your web site would be:
For example, my URL is:
After logging in to your web server account you need to issue the command '
cd public_html' to change your working directory to your *
public_html* folder where the files are stored that will make up your web site.
Your web pages are simple text files that have HTML tags that advise the browser how to render the look of your web page, including any images or hyperlinks are included on your web page. Once you place yourself in your *
public_html* folder you can use the *
vim* editor to create and modify your files. *
vim* is a modified (improved) version of the *
vi* editor. It is fairly easy to learn the handful of commands you need to create and maintain the files you'll need for the tasks in this guide. You can use the *
man vim* command at the Unix prompt to get helpful information about using the *
You will also need an SFTP (Secure File Transfer Protocol) client for your machine so you can upload any non-text files such as images, media (audio and video), and Java applets. If you are using a Windows machine, I recommend using FileZilla and for a Mac I recommend CyberDuck. Again, using the
bscacad3.buffalostate.edu server as an example, here are the necessary SFTP settings:
Another method for maintaining your web files is to use an HTML editor on your local machine to create and edit your files and then use one of the above mentioned SFTP clients to upload and download your files to your web server.
If all goes well your file should be listed in the left window.
On your Mac you can use the built-in application *
TextEdit* to edit your files and *
Fetch* to upload/download your files.
