I have been using my e mail. I find that there is no spell check, no fonts, no ability to change font color or size. Is this the way it is supposed to be?

I have started work on my web site. The text box seems to only be usable for one sentence at a time. I had planned an introductory paragraph. Do I have to put in a text box for every sentence?

thank you for your help
