Evolve Theme Version 4.3.7: Center “website-title” when there is no logo

Hi Evolve Theme Folks,
I am currently using Evolve Theme Version 4.3.7 for my website and I would like to know if there’s a way for me to center my website title, which is designated by the H1 tag with the ID of “website-title”, when both the Logo and Tagline are set to disabled. Currently, the “website-title” always appears left-justified and the only means for me to center it is through CSS.
Some example CSS rules I use to achieve this are:
.header > .row {
display: block;
}
.header #website-title {
text-align: center;
}
Is there any way to implement the above through the theme UI?
Any feedback would be greatly appreciated.
Best regards,
Matthew Huntley
