Answer 1

The following should work for you:

CSS:

.pageHelp{
    float:right;
    margin:10px 20px 0 0;
    width:85px;
    height:50px;
    border-radius:3px;
    background-color:#354E69;
    position:relative;
}

.pageHelp p{
    color:#000;
    padding:5px;
    text-align:center;
}

.pageHelp:after {
    content: ' ';
    height: 0;
    position: absolute;
    left:10px;
    width: 0;

    border: 10px solid transparent;
    border-left-color: #354E69;
    left: 100%;
    top: 50%;
    margin-top: -10px;
}​

HTML:

<div class="pageHelp"><p>In Page Help</p></div>​
