Lo que necesitas es editar la id "#header-blog" se encuentra dentro del <head> junto con todos los demás estilos.
Así está actualmente:
#header-blog{height:90px;padding:25px 0;background-color:#fff;position:relative;overflow:hidden}
Si no encuentras esto por alguna razon, debes agregar lo siguiente exactamente al final de todo el <head>
<style type="text/css">
#header-blog{height:90px;padding:25px 0;background-color:#fff;position:relative;overflow:hidden}
</style>
Y allí lo modificas como quieras.
ESTO ES LO QUE ESTA ACTUALMENTE. ME AYUDAS CON ESTO??
