Moving logo to the right

I have a website theme, Twofold, that automatically renders the logo to the centre and hides main nagivation under a button on the left. I wish to move the logo to the right instead of centre and have tried the code below in Additional CSS but nothing happened:

.site-logo {
padding: 30px 0;
text-align: right;
}

Through the forums also came across this;

header .site-tools {
width: 35%;
position: absolute;
top: 62px;
right: 20px;
}

But alas, no luck, logo still remains in the centre. Please help
