Themeforest Header Button Help

Hi All
Wonder if someone can help me before I tear my hair out!
Please go to this site and you will see 2 buttons in my header. I want to have the buttons on the same line but over towards the centre next to each other with a gap between them. I realise this has to be done in CSS and have found the relevant coding here header .alignright .dt-sc-bordered-button{padding:7px 126px; margin:1px;} but cannot figure out how to do this!

Also on the same home page below the menu wording Home, there is a blue line, any clues how to get rid of that!

Hereis hoping someone can help!
