Is a normal user allowed to view site's CSS sheet

I am looking at IDS (intrusion detection sensor) logs where some one tired to get a .css sheet through a URL. Ex: http://ift.tt/14Id44e - which throws a CSS sheet in the form of text file.

Is this allowed for any user or something to concern ?

I don't have much knowledge on these, so any help is appreciated. couldn't paste the output here, security concerns !!!

sample:

.homemidcontainer{  width: 900px;   background: #fff;}
.homeleftcol{   float: left;    width: 225px;   background-color: #FFFFFF;  height: 470px;}
.homerightcol{  float: right;   width: 675px;   height: 470px;  background-color: #FFFFFF;}
