If you need to add any of these codes when using Blogger click on the Edit HTML tab on top of the post your writing. I'm not sure how to add these on other platforms but I would suggest looking for something that says Edit HTML or something to that effect.
HTML is what helps make the internet go round after all. In this post I'm just going to cover some of the basic stuff but if your interested in getting a little more advanced with it (things like headings, tables, columns, meta tags, lists, etc.) Let me know in the comments!
To create a link back to your own blog follow this code:
<a href="http://www.YourBlogURLHere.com"> Your Blog Name Here </a>
This code will work on any blog that accepts HTML. Some sites do it automatically for you but in case they don't you now have the power to do it!
Giveaway Post I centered when it ends and some of the fine print.
If you find yourself having to manually center things because blogger is being a jerk use this code:
I went in and gave that a manual center effect so you could see how it formats it :)
To Italicize text use this code:
<i> Insert the sentence/word or anything you want Italicized.</i>
To make your text Bold use this code:
<b> Text that you want BOLD!</b>
To make your text Underlined use this code:
<u> Text that you want Underlined!</u>
P.s. I hope I didn't bore you all to death with this :x
