width 100%, no space on the left and right

Hello, i generate 5 columns shortcode and for every column there is an icon and down a title of the icon.
I add before the shortcode a div with the style “text-align center” and everything it’s in the center and it’s ok, but i would like to have the same width of the div with the text over, without white space on the left and on the right.
How i can make it?
This is the code:

<div style="text-align: center; width: 100%;">
