How to make a HTML list appear horizontally instead of vertically using CSS only?

问题

I need this because I want to make a menu (which is made from a HTML list) appear horizontally.

I prefer not to use absolute positioning since it might become messy when I start changing the layout of the page.

I would like also to remove the indenting of the sub-lists. Is it possible?

回答1:

You will have to use something like below

#menu ul{
  list-style: none;
}
#menu li{
  display: inline;
}
	

<div id="menu">
  <ul>
    <li>First menu item</li>
    <li>Second menu item</li>
    <li>Third menu item</li>
  </ul>
</div>

quite simple:

ul.yourlist li { float:left; }

or

ul.yourlist li { display:inline; }

回答3:

Using display: inline-flex

#menu ul {
  list-style: none;
  margin: 0;
  padding: 0;
  display: inline-flex
}

<div id="menu">
  <ul>
    <li>1 menu item</li>
    <li>2 menu item</li>
    <li>3 menu item</li>
  </ul>
</div>

Using display: inline-block

#menu ul {
  list-style: none;
  margin: 0;
  padding: 0;
}

#menu li {
  display: inline-block;
}

<div id="menu">
  <ul>
    <li>1 menu item</li>
    <li>2 menu item</li>
    <li>3 menu item</li>
  </ul>
</div>
