How can I increase or decrease the page width and site margin of a specific section on my front page.

Site URL: https://k2.life

I have about 8 image blocks next to one another. I want to make them so that they stretch out across the whole page section so that they fill in the blank space. If you navigate to my site it is the "Some of Our Recent Customers" section that I am referring to. Here is my current code that at least removes the padding, but I cannot seem to make them fill in the blank space from left to right.

#block-yui_3_17_2_1_1595186156795_32170,#block-yui_3_17_2_1_1595186156795_33500, #block-yui_3_17_2_1_1595186156795_35306, #block-yui_3_17_2_1_1595186156795_39012, #block-yui_3_17_2_1_1595186156795_59689, #block-yui_3_17_2_1_1595186156795_58146, #block-yui_3_17_2_1_1595186156795_56616, #block-yui_3_17_2_1_1595186156795_40813   {
  margin: 0 auto;
    padding: 0px !important;  
  max-width:1900px !important;
}

Looks like you figured it out?
