help me, is there anything that can explain the function of "footer" on the dashboard of word press? I am still new in this case thanks and regards
Footer is the part which appears in the bottom of your page. It's called footer.php file in the most themes. It contains, usually some links of theme creators, copyright, or sometimes you can add widgets in your footer. I hope this helps.
If you don't know what a footer is, you probably should start out with a lot of reading into HTML Basics. Once you've learned a little bit at least, learn Wordpress. This site here will help http://codex.wordpress.org
