Product & Categories 3 column (div) layout

After removing new CSS of version 3.1.1 my layout seems good, but the 3 columns are showed with 2 columns and the third column has a space.

When i change to 2 column seems OK, or 4 columns seems ok.

Hi,

Can you provide a link to a page with the issue so that we can look at the situation ?

My home page, this link: mysite.com/

The parameters of the link attached.

Before update the layout are ok without file modifications.

The issue comes from some customization.
You have the CSS:
.hkc-md-4 {
width: 33.66666566666533%;
}
in the customized frontend CSS of HikaShop. That CSS doesn't exist by default and that's this CSS which breaks the display since 33.6 * 3 is higher than 100% and thus it's not possible to have three elements of that width on the same line.
You'll have to fix your CSS and use something like we have by default instead:
.hkc-md-4 {
width: 33.33333333%;
}

Tks, solved
