Relative path means that you are specifying the location of a file or folder relative to the location of the current file or folder.
An example of a relative path in web development would be if you wanted to link to an image that is located in the same folder as your HTML file. You would type ../img/dog.jpg
into your HTML document and the browser would know to look for the img
folder inside of the folder that contains your HTML file and then find the file dog.jpg
inside of that folder.
