Mobile Half Menu, Right Side Justified

Site URL: https://www.rabbittdesign.net/

What a challenging thing to lookup, searched for an hour...
I have a half navigation drop down menu on my mobile site and want it to justify to the right side. Can't seem to find the CSS code for this.
If you solve this issue for me I would also love to be taught the correct terminology for everything that I am asking for so that I can re-tag this post and save some unfortunate soul from frustration.
Thank you in advance,
Rene Rabbitt

Just wanted to try and bump this up as I feel it may be useful to a number of users.

Hi @ReneRabbitt

Did you solve this? It looks like the mobile header menu and menu items are all right aligned. 

If not, can you provide more clarity on what you're trying to solve?

It isn't a permanent solve as I just justified by a specific number of pixels. Thank you so much for any help
here is what I have in CSS. I am a novice, the pixel bump was just to test it out really.

/* Half Width Mobile Menu */
.header-display-mobile .header-title-text {

.header-menu {

#page {

.header-menu-cta {

.header-menu-cta a {

Hi @ReneRabbitt

Oh okay, I understand. Replace your .header-menu style with the following:

.header-menu {
  	width: 60vw; 
	margin-left: auto; 
}

Hope that solved it
