I've been studying htlm and css lately, and wanted to practice so I stated writing one txt.I have put the txt and the image used in the same folder. I'm not sure what to do next though... I've tried reading online, but I couldn't find anything. DISCLAIMER: I know this might be a very trivial question, but then again it's better to ask and learn, right? :) Thanks so much! 
What is the next step after writing a .txt doc?
html
Try renaming the .txt file to a .html file.  You may be able to this through Windows Explorer if you can see extensions, or you may have to do it at the command line.One way could be: Open the .txt file in NotepadGo to Save as...Change the drop down of the type from *.txt (Text) to * (All Files)enter a filename and remember to put .html on the end.Thanks,
