Also, what size browser are you viewing the site from? I usually have my browser expanded all the way out on my laptop….but if I resize it a little bit the responsive css kicks in and then it adds a width of 620px to the widget area. So try changing that width to auto and it will look the exact same as the image above. This can be found on line 3885 –
.content,
.site-header .widget-area {
width: 620px;
}
Just change it to auto
and let me know the result.
