What is the difference between "~/" and ".. /" for directory navigation?

Question

I saw it somewhere, I wanted to know the difference.

Answer 1

Hi, come on, the / refers to the root of the OS directory (Unix architecture, in this case, via console), only the / access the root of your project, and, ../ the level above, see this practical example:

Imagine that you are creating a web application and have the following folder structure:

css
    style.css
    reset.css
images
    logo.png
    sprite.png
javascript
    main.js
    jquery.js
index.htm
about.htm

Now you want to format the class "logo", where, such class will have as background image the file logo.png (that’s in the folder images). Such a class will be part of the style.css file, it would look like this:

.logotipo {
        background: url('../images/logo.png');
}

To finish, the file style.css is in the folder css, and, to access the folder images it is necessary to return a level (so we use '../'), and after that access the folder with the logo, it was clear?

Hope I helped, hugs.
