How to create the search box like christiansong-lyrics

Hi ebbinjose. The easiest way to do this is using the built-in Header Ads sidebar in the theme v2.2.0:
1. Theme Options > Header > Header Ads ON.
2. In Widgets, drop a search widget into the Header Ads sidebar.
3. Add this css to your child theme style.css file, or use a custom css plugin like Simple Custom CSS.

#header-ads {
  width: 550px;
  margin-top: 18px;
  border: 10px solid #26272b;
}

One thing to note: the default Header Ads widget is hidden when the viewpost reaches 1200px width to leave room for the site title/logo and description. Also, if you want to change the default placeholder text in the search box, you’d need to copy searchform.php from the parent theme to your child theme and change the text there. Hope that helps get you started.
