how to align all my li on one line?

Solution 1:

Try putting white-space:nowrap; in your <ul> style

edit: and use 'inline' rather than 'inline-block' as other have pointed out (and I forgot)

Solution 2:

This works as you wish:

<html>
<head>
    <style type="text/css"> 

ul
{ 
overflow-x:hidden;
white-space:nowrap; 
height: 1em;
width: 100%;
} 

li
{ 
display:inline; 
}       
    </style>
</head>
<body>

<ul> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
</ul> 

</body>
</html>

Solution 3:

Using Display: table

HTML:

<ul class="my-row">
    <li>1</li>
    <li>2</li>
    <li>3</li>
</ul>

CSS:

ul.my-row {
  display: table;
  width: 100%;
  text-align: center;
}

ul.my-row > li {
  display: table-cell;
}

SCSS:

ul {
  &.my-row {
    display: table;
    width: 100%;
    text-align: center;
    
    > li {
      display: table-cell;
    }
  } 
}

Works great for me

Solution 4:

Here is what you want. In this case you do not want the list items to be treated as blocks that can wrap.

li{display:inline}
ul{overflow:hidden}
