Reply To: 3 Column Responsive Images – 33.333% not working in Codepen?

[Paulie_D]

Am I missing something easy?

Yes….three times 33.3% does equal 100% but then you are adding in margins so the width will add up to more that 100% of the total width of the wrapper.

So…the images cannot be 33.3% wide but rather [ (100% – 100px) / 3 ]percent wide.

You could use calc for this but that will depend on what browser support you need.
