This is the first paragraph. Notice that XHTML and HTML do not wrap when I go down to the next line. They wrap when they need to based on the screen. Notice that I have now moved down to the next line. XHTML and HTML did not move to the next line. Notice that I just left multiple spaces. These spaces were not acknowledge by XHTML and HTML. Now I will end the paragrah and start a new one.
Notice that there is a line between paragraphs. The code shown introduces spaces into the line.
