Image doesnt expand entire width on high resolutions

Question

I have a website which is using the Golden Grid System. You can see my site here http://syndicatebox.com/helpout/index_fix.html

On low resolutions as in the screenshot below you can see the top two images span equally and they look correct.

But below if you look if im over lets say 1980x1080 the top two images retain there size and dont expand the entire width equally.

I have my code here but I have no idea what i am doing wrong.

Answer 1

It's because of media queries Remove following code from you style.css

line no. 373 and 376

#twoway .wrapper:first-child {
/* margin-left: 25%; */
}
@media screen and (min-width: 117em)
#twoway .wrapper {
/* width: 25%; */
}
