Expand width of space allowed for logos

Hello:

This is the page I am working on: https://greatnonprofits.org/partners
I am looking to expand the width of my page so that I can fit more than 2 partner logos per line. It lets me put 3-4 horizontally on my editing page but does not upload the same way.
I do not code but is there anything I can change in here:

<p><span style="color: #000000; line-height: 27px;"><strong><span style="font-size: small;"><span style="color: #9fbd5f;"><span style="font-size: medium;"><span style="color: #9fbd5f;">Partners</span></span>:</span></span></strong></span></p>

<p><img src="https://greatnonprofits.org/wordpress/wp-content/uploads/2011/01/ALSF-Horizontal-4C.jpg" alt="" width="250" height="58" /> <img src="https://greatnonprofits.org/wordpress/wp-content/uploads/2011/01/logo-jpeg.jpg" alt="" width="125" height="117" /></p>

Any advice would be greatfully appreciated!

Thanks!
