HI,

Oh, this is exactly the same. Please read in offcial CSS manual (W3C).

You are right. Me bad. I already deleted the 2.0.8 update so made a little mistake.

It is

.sp-simpleportfolio .sp-simpleportfolio-filter>ul>li{float:left;display:block;margin:0 5px 5px 0}

Check spsimpleportfolio.css (2.0.8)

.sp-simpleportfolio{padding:0}.sp-simpleportfolio:after,.sp-simpleportfolio:before{content:" ";display:table}.sp-simpleportfolio:after{clear:both}.sp-simpleportfolio .sp-simpleportfolio-img{display:block;max-width:100%;height:auto}.sp-simpleportfolio .sp-simpleportfolio-filter{text-align:center;margin-bottom:30px}.sp-simpleportfolio .sp-simpleportfolio-filter>ul{list-style:none;padding:0;margin:0;display:inline-block}.sp-simpleportfolio .sp-simpleportfolio-filter>ul>li{float:left;display:block;margin:0 5px 5px 0}

For 2.0.7

.sp-simpleportfolio{padding:0}.sp-simpleportfolio:after,.sp-simpleportfolio:before{content:" ";display:table}.sp-simpleportfolio:after{clear:both}.sp-simpleportfolio .sp-simpleportfolio-img{display:block;max-width:100%;height:auto}.sp-simpleportfolio .sp-simpleportfolio-filter{text-align:center;margin-bottom:30px}.sp-simpleportfolio .sp-simpleportfolio-filter>ul{list-style:none;padding:0;margin:0;display:inline-block}.sp-simpleportfolio .sp-simpleportfolio-filter>ul>li{float:left;display:block;margin:0 5px}

I would keep this update, becuase it works better in J5 and PHP 8.3

it's easier to override one line of Custom CSS than have real code problems.

But you'll do as you like, it's your website.
