Why can't i add a new slide to my pure css slideshow?

Question

This is my code, when i run it with 5 images it works fine. Now when i add a 6th images it doesnt work anymore. It is somehow showing the images in the 1st slide or with bigger images on the 5th slide. Tried many things can't figure it out. I thougth it was the float but that isn't it so i don't know anymore. The arrows arrent showing up so i used white boxes :).

This is my css and html:

 .sp-slideshow { position: relative; margin: 10px auto; width: 65%; max-width: 1000px; min-width: 260px; height: 60%; border: 10px solid #fff; border: 10px solid rgba(255, 255, 255, 0.9); box-shadow: 0 2px 6px rgba(0, 0, 0, 0.2); } .sp-content { width: 100%; height: 100%; overflow: hidden; position: relative; } .sp-slideshow input { position: absolute; bottom: 15px; left: 50%; width: 9px; height: 9px; z-index: 1001; cursor: pointer; opacity: 0; } .sp-slideshow input+label { position: absolute; bottom: 15px; left: 50%; width: 6px; height: 6px; display: block; z-index: 1000; border: 3px solid #fff; border: 3px solid rgba(255, 255, 255, 0.9); border-radius: 50%; transition: background-color linear 0.1s; } .sp-slideshow input:checked+label { background-color: #fff; background-color: rgba(255, 255, 255, 0.9); } .sp-selector-1, .button-label-1 { margin-left: -36px; } .sp-selector-2, .button-label-2 { margin-left: -18px; } .sp-selector-4, .button-label-4 { margin-left: 18px; } .sp-selector-5, .button-label-5 { margin-left: 36px; } .sp-selector-6, .button-label-6 { margin-left: 54px; } .sp-arrow { position: absolute; top: 50%; width: 28px; height: 38px; margin-top: -19px; display: none; cursor: pointer; z-index: 1000; background: transparent url(arrows.png) no-repeat; background-color:white; transition: opacity linear 0.3s; } .sp-arrow:hover { opacity: 1; } .sp-arrow:active { margin-top: -18px; } .sp-selector-1:checked~.sp-arrow.sp-a2, .sp-selector-2:checked~.sp-arrow.sp-a3, .sp-selector-3:checked~.sp-arrow.sp-a4, .sp-selector-4:checked~.sp-arrow.sp-a5, .sp-selector-5:checked~.sp-arrow.sp-a6 { right: 15px; display: block; background-position: top right; } .sp-selector-2:checked~.sp-arrow.sp-a1, .sp-selector-3:checked~.sp-arrow.sp-a2, .sp-selector-4:checked~.sp-arrow.sp-a3, .sp-selector-5:checked~.sp-arrow.sp-a4, .sp-selector-6:checked~.sp-arrow.sp-a5 { left: 15px; display: block; background-position: top left; } input.sp-selector-1:checked~.sp-content { background-position: 0 0; background-color: lightblue; } input.sp-selector-2:checked~.sp-content { background-position: -100px 0; background-color: lightcoral; } input.sp-selector-3:checked~.sp-content { background-position: -200px 0; background-color: lightgoldenrodyellow; } input.sp-selector-4:checked~.sp-content { background-position: -300px 0; background-color: lightgreen; } input.sp-selector-5:checked~.sp-content { background-position: -400px 0; background-color: lightpink; } input.sp-selector-6:checked~.sp-content { background-position: -500px 0; background-color: red; } .sp-slider { position: relative; left: 0; width: 500%; height: 100%; list-style: none; margin: 0; padding: 0; transition: left ease-in 0.8s; } .sp-slider>li { color: #fff; width: 20%; box-sizing: border-box; float: left; text-align: center; position: relative; } .sp-slider>li img { box-sizing: border-box; display: block; margin: 0 auto; max-height: 100%; max-width: 100%; } input.sp-selector-1:checked~.sp-content .sp-slider { left: 0; } input.sp-selector-2:checked~.sp-content .sp-slider { left: -100%; } input.sp-selector-3:checked~.sp-content .sp-slider { left: -200%; } input.sp-selector-4:checked~.sp-content .sp-slider { left: -300%; } input.sp-selector-5:checked~.sp-content .sp-slider { left: -400%; } input.sp-selector-6:checked~.sp-content .sp-slider { left: -500%; } input.sp-selector-1:checked~.sp-content .sp-slider>li:first-child, input.sp-selector-2:checked~.sp-content .sp-slider>li:nth-child(2), input.sp-selector-3:checked~.sp-content .sp-slider>li:nth-child(3), input.sp-selector-4:checked~.sp-content .sp-slider>li:nth-child(4), input.sp-selector-5:checked~.sp-content .sp-slider>li:nth-child(5), input.sp-selector-6:checked~.sp-content .sp-slider>li:nth-child(6) { opacity: 1; }

Answer 1

6 images should make container 600%

6 image should be 16.66% each of the container

.sp-slider {
    position: relative;
    left: 0;
    width: 600%;/* ============  6 images of 100% width */
    height: 100%;
    list-style: none;
    margin: 0;
    padding: 0;
    transition: left ease-in 0.8s;
}

.sp-slider > li {
  color: #fff;
  width: 16.66%;/* =====!  X6 = 100% width of parent container */
  box-sizing: border-box;
  float: left;
  text-align: center;
  position: relative;
}
