Is there a way to select and apply styles to a div that is nested within another div without any id or class?
<div class="wrapper">
<div>
</div>
<div>
</div>
<div>
</div>
</div>
What's the best way to target, for instance, div two in this structure?
.container > section:nth-child(1) {
//styling instructions for the first section that is a child of .container
}
.container > section:nth-child(2) {
//styling instructions for the second section that is a child of .container
}
Remember to use the > symbol to specifically target direct children and not all descendants.
.wrapper div:nth-child(2) {
color: red;
}
nth-child is a handy tool for selecting specific elements in CSS. In addition to first-child and last-child, you can also utilize different functions like 3n+0 to target every third item starting from 0. Take a look at this codepen for demonstration.
Furthermore, there's the option of using nth-of-type(2) which alters every second occurrence of a certain pattern. You can find an illustration of this concept in the same codepen.
.container div:nth-child(2) {
background: blue;
height:200px;
width:200px;
}
When you specify a number in nth-child, it selects that specific child within the container. In this case, it targets the second div.

Using Descendant Selectors can be problematic, as it is not efficient and can easily break when there are changes made to the HTML structure. It is recommended to create new CSS class selectors instead.
// avoid
.wrapper div {..}
// prefer
.inner-div {..}
.selecting-this {..}
.or-this {..}
<div class="wrapper">
<div class="inner-div">
</div>
<div class="selecting-this">
</div>
<div class="or-this">
</div>
<div class="inner-div">
</div>
</div>
However, if you cannot modify the HTML structure:
.wrapper div {..}
When using a space in the selector, it looks for child elements with the tag div WITHIN an element with the specified class .wrapper
