Please take a look at this screenshot:
I'm trying to justify the spacing between those two li's to be constant at 35px, It's a WordPress menu, here's the code for the menu:
<style>
.main-navigation li {
margin: 0 0px 0px 40px;
position: relative;
}
</style>
<li id="menu-item" class="menu-item"><a href="#"><i class="fa "></i><span>حملات</span></a>
</li>
