Li item on two lines. Second line has no margin

问题:

I'm currently working on an unordered list containing list items with taglines. I'm having a problem concerning one list item, which is long enough to take up two lines (See image)

I want it so that the second line is aligned with the first line. This is the HTML code i'm using. I used fontAwesome for the check images.

ul {
  width: 300px;
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css" rel="stylesheet"/>
<ul class="fa-ul custom-list">
  <li><i class="fa fa-check fa-fw"></i>List item on 1 line</li>
  <li><i class="fa fa-check fa-fw"></i>List item on 1 line</li>
  <li><i class="fa fa-check fa-fw"></i>This is a list item that actually takes up 2 lines. Looks ugly</li>
</ul>

I already tried to enter multiple   in between '2' and 'lines' but that seems like a really bad practice to me. I hope someone can help me with this problem.

This is because the tick is inline content so when the text wraps it will continue to flow as usual.

You can stop this behaviour by taking advantage of text-indent:

The text-indent property specifies how much horizontal space should be left before the beginning of the first line of the text content of an element.

text-indent (https://developer.mozilla.org/en-US/docs/Web/CSS/text-indent)

By supplying a negative text-indent you can tell the first line to shift a desired amount to the left. If you then specify a positive padding-left you can cancel this offset out.

In the following example a value of 1.28571429em is used because it is the width set on the .fa-fw by font-awesome.

ul {
  width: 300px;
}
li {
    padding-left: 1.28571429em;
    text-indent: -1.28571429em;
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css" rel="stylesheet"/>
<ul class="fa-ul custom-list">
    <li><i class="fa fa-check fa-fw"></i>List item on 1 line</li>
    <li><i class="fa fa-check fa-fw"></i>List item on 1 line</li>
    <li><i class="fa fa-check fa-fw"></i>This is a list item that actually takes up 2 lines. Looks ugly</li>
</ul>

回答2:

you can just add this to your ul:

ul {
text-indent:-20px; 
margin-left:20px;
}

You could remove the check out of the page flow by setting them with position:absolute

ul {
  width: 300px;
}
.fa-fw {
  position: absolute;
  left: -22px;
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css" rel="stylesheet" />
<ul class="fa-ul custom-list">
  <li><i class="fa fa-check fa-fw"></i>List item on 1 line</li>
  <li><i class="fa fa-check fa-fw"></i>List item on 1 line</li>
  <li><i class="fa fa-check fa-fw"></i>This is a list item that actually takes up 2 lines. Looks ugly</li>
</ul>

You can use "display:table" as style for li, and inside create a span with "display:table-cell" styling. Or create corresponding class. Like this:

<li style="display:table"><span style="display:table-cell">text with 
all lines indented</span></li>

回答5:

you can put your text in a div and give float:left to your inner li and div.

回答6:

I found this does not work reliably across all browsers and devices.

This code does:

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}
