Which html code is used for letters appearing in the case that they were typed?

On my tumblr, I’m using a theme that makes all the letters on my page lowercase. I’d like them to appear the way they are here, so when I type a capital letter, it appears uppercase, and so on and so forth. I’m not advanced with html codes, but I know enough to figure out a few basic things.

You’ll need to edit the CSS file and search for the text-transform property with a value of lowercase. Remove that line completely and you should be set.

Go through the code and remove the part that says text-transform: lowercase or change it to read text-transform: normal
