Hello,
This is just custom HTML input with a radio button using the -gray module class suffix in the top_row2_2 position. The styling for the chat itself will use the default styling of whatever extension you choose to use in this position.
The default coding we used in the module is below:<p><img src="images/chaticon.png" alt="phone icon" style="float: left; padding-right: 25px;" /> <span class="s5_highlightcolor" style="display: block; padding-top: 16px;">We are available 24/7 to answer your questions. We specialize in customer service. </span> <input class="button" type="submit" name="submitBtn" value="Live Chat" /></p>
