Text Align justify - editing html code of your blog template

A blogger like me struggles to actually bring his imagination about layout into reality by modifying the html code. I had always wanted to 'justify' the posts in my blog. I have been using a custom pre-post template for that which is a bit tedious. I just discovered the possibility of doing it by simply modifying or actually adding a small line in the html code of the template. I added

text-align: justify;

in the code of the main wrapper. Let me check hot is works.
