Reduce Width Of Boxed

I have reduced the body.boxed .dexp-body-inner { background: #FFFFFF; max-width: 1070px; In the preset1.css But all the blocks are too wide thanks

We are using lessc for theme style, the css will be complied automatically by system, If you want to change style, you have to change it in less file. In this case, please change it in style.less (line 10) file under lessc folder. Thanks!
