CSS: using syntax to target element by its unique identifier

Check out this guide:

I followed the instructions and used an external stylesheet. I added #menu before each CSS item, for example:

#menu ul{
font-family: Arial, Verdana;
font-size: 14px;
margin: 0;
padding: 0;
list-style: none;}

or:

#menu ul li{
display: block;
position: relative;
float: left;}

However, despite referencing with #menu, the menu does not display correctly. The styling is not applied to the parent 'li' element.

Any suggestions?

Thanks, Dave

Answer №1

Here is the HTML code you provided:

<ul id="menu">

In order to style this correctly, your CSS should look like this:

ul#menu

Currently, your CSS is targeting an 'LI inside of a UL that is within another element with an ID of MENU'

Answer №2

The target for #menu ul is any unordered list (ul) inside an element with the ID of 'menu'...

<div id="menu">
    <ul> <!-- <<-- this element is the target -->
       ...
    </ul>
</div>

(The example uses a div, but any element with id="menu" can be used)


The target for ul#menu is a specific unordered list (ul) with the ID of 'menu'...

<ul id="menu">  <!-- <<-- this element is the target -->
    ...
</ul>

Based on comments:

Quote: "...i am missing the 'box' around the parent node."

The element you are referring to, just inside the parent <ul id='menu'>, is the <li>. You have not targeted it at all.

To style this element, add ul#menu li a to your CSS. (Note the comma, separating two unique selectors with shared styling.)

ul#menu li a,
ul#menu ul li a {
  display: block;
  text-decoration: none;
  color: #ffffff;
  border-top: 1px solid #ffffff;
  padding: 5px 15px 5px 15px;
  background: #2C5463;
  margin-left: 1px;
  white-space: nowrap;
}

Do you see the difference?

ul#menu is the parent. ul#menu li is the first child inside the parent. ul#menu li a is the link inside the first child of the parent.

Since ul#menu li targets all <li> elements that are children of ul#menu, you only need one selector...

ul#menu li a {
  display: block;
  text-decoration: none;
  color: #ffffff;
  border-top: 1px solid #ffffff;
  padding: 5px 15px 5px 15px;
  background: #2C5463;
  margin-left: 1px;
  white-space: nowrap;
}

Notice how it spans the full width of the screen.

To specifically target and style the parent, add this to your CSS:

ul#menu {
  display: block;
  position: relative;
  float: left;
  list-style: none;
}
