I have a few random blocks. Whenever a block falls in the new row, I am making it look different. When the user clicks on a button, I hide few blocks by `display:none`, and the problem occurs. The `nth-child` selector also counts hidden elements.

Is there way to ignore those specific blocks, so that again every row has a different style? This is an example of a similar scenario.

```js
$('.hide-others').click(function () {
    $('.css--all-photo').toggleClass('hidden');
})
```

```css
.board-item--inner {
    height:200px;
    background:tomato;
    text-align:center;
    color:#fff;
    font-size:33px;
    margin-bottom:15px;
    border:2px solid tomato;
}
@media (min-width:768px) and (max-width:991px) {
    .board-item:nth-child(2n+1) .board-item--inner {
        border:2px solid #000;
        background:yellow;
        color:#000;
    }
}
@media (min-width:992px) and (max-width:1199px) {
  .board-item:nth-child(3n+1) .board-item--inner {
    border:2px solid #000;
    background:yellow;
    color:#000;
  }
}
@media (min-width:1200px) {
  .board-item:nth-child(4n+1) .board-item--inner {
    border:2px solid #000;
    background:yellow;
    color:#000;
  } 
}
```

Simply go through the snippet or [EXTERNAL FIDDLE](https://jsfiddle.net/happy2deepak/g7gL5zfb/4/), and you'll get my question.

I am specifically looking for a pure CSS solution.
**Please provide a fiddle for your answers!** And I cannot remove those blocks permanently, my user has the option to filter files on button click, that is why hidden and shown scenario.
