How to Bypass Hidden Elements When Using nth-child Selectors
The nth-child selector allows you to target elements based on their position among their sibling elements. However, this selector counts hidden elements, which can cause problems when you want specific rows in a grid to display differently.
In your case, you're using nth-child selectors to change the appearance of every nth row in a grid of blocks. When you hide some blocks using display: none, the nth-child selector still counts them, leading to incorrect styling.
CSS-Based Solution
Unfortunately, there's no pure CSS solution to this problem. The nth-child selector simply looks at all siblings, regardless of their visibility.
jQuery-Based Solution
To avoid including hidden elements in your nth-child calculations, you need to remove them from the DOM when they're hidden. jQuery provides a .detach() method for this purpose:
$(".hide-others").click(function () {
var divs;
$(".photos-board-item").each(function (i) {
$(this).data("initial-index", i);
});
if (divs) {
$(divs)
.appendTo(".row")
.each(function () {
var oldIndex = $(this).data("initial-index");
$(".photos-board-item").eq(oldIndex).before(this);
});
divs = null;
} else {
divs = $(".css--all-photo").detach();
}
});
This code removes the hidden elements from the DOM when the "Hide others" button is clicked. When the button is clicked again, the elements are reinserted into the DOM, preserving their original order.
Demo
Here's a demo that demonstrates the solution:

By using the .detach() method, you can toggle the visibility of elements without breaking the nth-child selector logic, ensuring that every row in your grid maintains its desired appearance.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
