Hello Jensen – Please try the DOM Element as .main-wrap
However, we see that the slider at the top is full-width and might not allow you to click the background, just for the height of that section. In case you want to be able to click that area as well, you can use the following CSS Snippet:
.common-slider.grid-b-slider{
max-width: 1170px;
margin:38px auto 0;
}
