Adding a css to my blog

I noticed that I don't find optimal to find what is commands entry from clear text on my blog so surfing around I found this css entry that I am will start applying whenever I enter a command or code to the page.

On Blogger, on the Layout tab I selected "edit html" and added the following:

/* Added by RB

.command{ padding:1em;
border:1px
dashed #2f6fab;
color:black;
background-color:#f9f9f9;
line-height:1.1em;
font-family:Courier New,Courier,mono;
font-size:12px;
font-style:italic
}

Example:

tar -xzvf speex-1.2rc1.tar.gz
