How do I select only first-level children of an element [closed]

Question

How do I select all the first-level div elements marked below:

<div>
  <a>         //
    <span></span>
  </a>
  <ul>         //
    <li></li>
    <li></li>
  </ul>
  <div>         //
    <div></div>
  </div>
  <span>         //
  </span>
</div>

When I use the wildcard selector it also selects the descendants. I only want the first-level children. How do I do it with css only?

You could go with a CSS reset rule for this issue.

First you set your style as you want it to look on your first level child elements, the you can use a reset rule parentEl -> everything -> everything --> #el > * > * to reset the style back to its default settings. Essentially this says every child element of every child element that is a child of the parent element.

NOTE: Keep in mind that anything you style in the initial first-level of children will need to be reset to its default style within the div > * > * reset rule.

Though this is not needed, you could use the :root to set your default styles as css variables, so you have them all in one area, your root elements properties, and then call them on your reset css properties.

See the following snippit:

:root {
  --def-color: black; 
}

div > * {
  color: red;
}
/* reset rule */
div > * > * {
  color: var(--def-color);
}

<div>
  <a>child level 1    //   
    <span>span child lvl 2</span>
    <div>div child lvl 2</div>
  </a>
  <ul>ul child level 1        //
    <li>li child level 2</li>
    <li>li child level 2</li>
    <li>
      <ul>ul child lvl 3
        <li>li child level 4</li>
      </ul>
    </li>
  </ul>
  <div>child level 1         //
    <div>child level 2
      <div>child level 3</div>
    </div>
  </div>
  <span>child level 1       //
  </span>
</div>
