change font site title

Hi, I have tried a couple solutions I have found in this forum, but it didn't work so far... www.katrien.co 1. I would like to change the font of the site title into the font Allura and make it bigger. I have tried to insert this in custom css: } h1#site-title { font-size: 60px; font-family: ‘Allura’; font-weight:normal; padding-bottom:0px; } 2. How can I delete that light blue box in my slider? Thanks for your help!! Kat
