In addition to my original question, I would also like to control the page title font size. I thought I found the css code, but not sure as any changes to this are not responsive. When I attempt to change the font size of 42px nothing happens. Am I looking in the wrong area of the css? Thank you.

#page-title {width:940px; margin:0 auto; height:250px; }
#page-title h2 {font-size:42px; colour:#fff; text-shadow:1px 1px 2px #000000; line-height:44px; position:relative; z-index:4; top:165px;}

1.

#page-title {
width: 940px;
margin: 0 auto;
height: xxx px;
}

2. That is correct.. if it's not working add an !important

#page-title h2 {
font-size: xxxpx !important;
color:
white;
text-shadow: 1px 1px 2px
black;
line-height: 44px;
position: relative;
z-index: 4;
top: 165px;
}

So here's an interesting observation as I originally thought the answers are what you provided. I made the changes to the standard.css file through the wordpress editor with no success and was puzzled why it didn't work. So, I ftp'd in to the momento theme on my server and see that there is actually two standard.css files - one in the root of the theme directory and another in a sub-directory labeled "css". It appears that the wordpress editor calls to the standard.css in the root folder, while your theme calls to the same file that resides in the "css" sub-directory. So I just made the changes the standard.css file using a css editor and uploaded in to css sub-directory.

Success!
