Change the menu side for the other side

Dear Support,
I have installed the Hiero Theme and would like to know if I can change the side menu to the left side.
my site:
Thank you very much, I await your response!


Actually, there is no option on the theme to do that, bu here is the simple trick to move the sidebar to the right:

.content-area {
    float: right;
    width: 70%;
    padding-left: 25px;
.site-content {
    margin: 0;
.site-sidebar {
    float: right;

Put the code into Customize > Additional CSS.
