Paragraph, Bold, and Italic
If you create a paragraph in your website, surround the paragraph with (p) and (/p). It will automatically create a space if you add a paragraph code within each paragraph. When bolding key words within a website, use the letter b. You can put these around single words or an entire sentence. Italize is the same way. Add the code (i) within a sentence to italize words. This code is to be place directly in HTML however you could do it in CSS to make it faster and easier.
Breaks, Lines, and White Space
When you want to create a space in between paragraph, you cannot create an extra space manually through the HTML because the program will not understand. To create that extra space you need to add a break (br). You can add as many breaks to create that desired space. You can also create lines in between sentences. This code is (hr) and is placed in the HTML after the sentence.
Background Color
To create a background, there are different types of colors to use. You can use RGB values which is how much red, green, and blue is used. Another option is hex codes. This is a 6 digit code representing a specific color. Lastly there are 147 defined colors in the system. There is no code but the name of the color. To get a color behind text, you have to mention where you want it, like header, body, main, or footer.
