Find out What Fonts Family a Website is Using

1. Font color
2. Background color
3. Font family
4. Font being rendered
5. Font size
6. Line-height, vertical-align, letter and word spacing
7. Font weight, style, variant
8. Text transform, decoration, align and indent
9. Element's type, class or ID

You can now easily see what is the hexadecimal or rgb color code of the highlighted text, what font family and font size is used and how the font is aligned and spaced along with what CSS class or CSS ID is used to style the font. You can then check the source code of the webpage to find out the CSS code for this font style.

I just hope it helps you in better experience the web and in better understanding designing. Have fun! :))
