Boldface and Italic are standard markup instructions. They can be nested to produce text that is both bold and italic. The nesting order is unimportant so long as the inline elements are properly nested. Inline elements are not just for whole words or phrases, but can be applied inside words. The HTML code may look funny in that case, but the tags do not appear in the web page. Since browsers ignore spaces, this will not cause a line break just as extra spaces between words will not have any effect. We will have to force a line break here.
Big text or small text, how do you like your text? We like monospace text for programming code
for(x=1;x<=10;x++)
so it stands out from the rest of the text.

It's all just text. Text.Text.Text.
