It depends which part you want to align left. For example, to make everything on the homepage align left you can adjust the responsive css that kicks in when viewing in mobile devices –
.welcome-feature-1,
.welcome-feature-2,
.welcome-feature-3,
.home-feature-1,
.home-feature-2,
.home-feature-3,
.home-feature-4,
.home-feature-1,
.home-feature-2,
.home-feature-3,
.home-feature-4,
.home-feature-5,
.home-feature-6,
.home-feature-7,
.home-feature-8,
.home-feature-9,
.home-feature-10,
.home-feature-11,
.home-feature-12,
.home-feature-13,
.home-feature-14 {
margin: 0 auto;
text-align: center;
width: 100%;
}The above code is around line 4114 in the default Epik css file. If you’ve made changes then it may be located on another line.
Change the code that says "center" to left and that’s it, for that part.
