I have an (XHTML Strict) page where I float an image alongside regular paragraphs of text. All goes well, except when a list is used instead of paragraphs. The bullets of the list overlap the floated image.

Changing the margin of the list or the list items does not help. The margin is calculated from the left of the page, but the float pushes the list items to the right inside the li itself. So the margin only helps if I make it wider than the image.

Floating the list next to the image also works, but I don't know when the list is next to a float. I don't want to float every list in my content just to fix this. Also, floating left messes up the layout when an image is floated to the right instead of left of the list.

Setting li { list-style-position: inside } does move the bullets along with the content, but it also causes lines that wrap to start aligned with the bullet, instead of aligned with the line above.

The problem is obviously caused by the bullet being rendered outside the box, the float pushing the开发者_开发问答 contents of the box to the right (not the box itself). This is how IE and FF handle the situation, and as far as I know, not wrong according to the spec. The question is, how can I prevent it?

I have found a solution to this problem. Applying an ul { overflow: hidden; } to the ul ensures that the box itself is pushed aside by the float, instead of the contents of the box.

Only IE6 needs an ul { zoom: 1; } in our conditional comments to make sure the ul has layout.

Adding an improvement to Glen E. Ivey's solution:

ul {
    list-style: outside disc;
    margin-left: 1em;
}
ul li {
    position: relative;
    left: 1em;
    padding-right: 1em;    
}​

http://jsfiddle.net/mblase75/TJELt/

I prefer this technique, since it works when the list needs to flow around the floating image, while the overflow: hidden technique will not. However, it's also necessary to add padding-right: 1em to the li to keep them from overflowing their container.

---

This is where the "display" property comes into its own. Set the CSS below to make the list work alongside the floated content.

display: table; works alongside floated content (filling the gap) but without hiding content behind it. Much like a table does :-)

.img {
  float: left;
}

.table {
  display: table;
}

<img class="img" src="https://via.placeholder.com/350x350" alt="">
<ul>
  <li>Test content</li>
  <li>Test content</li>
  <li>Test content</li>
</ul>
<ul class="table">
  <li>Test content</li>
  <li>Test content</li>
  <li>Test content</li>
</ul>

EDIT: Remember to add a class to isolate which lists you wish to do this for. E.g. "ul.in-content" or more generally ".content ul"

---

Try list-style-position: inside to change the layout of the bullets.

Why overflow: hidden works

The solution is as easy as:

ul {overflow: hidden;}

A block box with overflow: other than visible establishes a new block formatting context for its contents. W3C recommendation: http://www.w3.org/TR/CSS2/visuren.html#block-formatting

Example

The buttons on my website, which are <li> in disguise, are made like this. Make the viewport (window) of your browser smaller to see the indenting in action.

At http://archivist.incutio.com/viewlist/css-discuss/106382 I found a suggestion that worked for me: style the 'li' elements with:

position: relative;
left: 1em;

Where you replace "1em" with the width of the left padding/margin that your list items would have if the float weren't present. This works great in my application, even handling the case where the bottom of the float occurs in the middle of the lists--the bullets shift back over to the (local) left margin just right.

---

By adding overflow: auto; to your ul works for me at least.

Update

I've updated my jsfiddle to visualize what's going on. When having the ul beside the floating img, the content of the ul will be pushed by the float, but not the actual container. By adding overflow: auto the whole ul-box will be pushed by the float instead of only the content.

---

You could assign position: relative; left: 10px; to the li. (You may additionally want to give it a margin-right: 10px;, otherwise it might become too wide on the right side.)

Or, if you want to use float for the ul -- as suggested by others -- you can probably stop the rest from floating right of the ul by using clear: left on the element that follows the ul.

Disclaimer

Lists next to floated elements cause issues. In my opinion, the best way to prevent these sorts of floating issues is to avoid floating images that intersect with content. It'll also help when you have to support responsive design.

A simple design of having centered images between paragraphs will look very attractive and be much easier to support than trying to get too fancy. It's also one step away from a <figure>.

But I really want floated images!

Ok, so if you're crazy persistent enough to continue down this path, there are a couple techniques that can be used.

The simplest is to make the list use overflow: hidden or overflow: scroll so that the list is essentially shrink wrapped which pulls the padding back to where it's useful:

img {
  float: left;
}
.wrapping-list {
  overflow: hidden;
  padding-left: 40px;
}

<img src="http://placehold.it/100x100"/>
<ul class="wrapping-list">
  <li>lorem</li>
  <li>ipsum</li>
  <li>dolor</li>
  <li>sit</li>
  <li>amet</li>
</ul>

This technique has a few problems though. If the list gets long, it doesn't actually wrap around the image, which pretty much defeats the entire purpose of using float on the image.

img {
  float: left;
}
.wrapping-list {
  overflow: hidden;
  padding-left: 40px;
}

<img src="http://placehold.it/100x100"/>
<ul class="wrapping-list">
  <li>lorem</li>
  <li>ipsum</li>
  <li>dolor</li>
  <li>sit</li>
  <li>amet</li>
  <li>lorem</li>
  <li>ipsum</li>
  <li>dolor</li>
  <li>sit</li>
  <li>amet</li>
  <li>lorem</li>
  <li>ipsum</li>
  <li>dolor</li>
  <li>sit</li>
  <li>amet</li>
</ul>

But I really want wrapping lists!

Ok, so if you're even crazier more persistent and you absolutely must continue down this path, there's another technique that can be used to wrap the list items and maintain bullets.

Instead of padding the <ul> and trying to get it to behave nicely with bullets (which it never seems to want to do), take those bullets away from the <ul> and give them to the <li>s. Bullets are dangerous, and the <ul> just isn't responsible enough to handle them properly.

img {
  float: left;
}
.wrapping-list {
  padding: 0;
  list-style-position: inside;
}
.wrapping-list li {
  overflow: hidden;
  padding-left: 25px;
}

<img src="http://placehold.it/100x100"/>
<ul class="wrapping-list">
  <li>lorem</li>
  <li>ipsum</li>
  <li>dolor</li>
  <li>sit</li>
  <li>amet</li>
  <li>lorem</li>
  <li>ipsum</li>
  <li>dolor</li>
  <li>sit</li>
  <li>amet</li>
  <li>lorem</li>
  <li>ipsum</li>
  <li>dolor</li>
  <li>sit</li>
  <li>amet</li>
</ul>

This wrapping behavior can do weird things to complex content, so I don't recommend adding it by default. It's much easier to set it up as something that can be opted into rather than something that has to be overridden.

I am using this to solve this problem:

ul {
   display: table;
}

---

Try the following on your UL tag. This should take care of the bullets overlaying your image and you don't have to mess up your left allignment caused by list-position: inside.

overflow: hidden; 
padding-left: 2em; 

---

Struggled with this myself. Best I've managed is the following:

ul {
    list-style-position: inside;
    padding-left: 1em;
    text-indent: -1em;
}

The text is not actually indented but the bullet shows.

---

After fighting with this interesting issue in several projects, and investigating why it happens, I finally believe I found both: a working and 'responsive' solution.

Here is the magic trick, live example: http://jsfiddle.net/superKalo/phabbtnx/

ul {
    list-style: none;
    position: relative;
    padding-left: 0; /* remove any left padding */
    margin-left: 0; /* remove any left margin */
    left: 35px;
}
li {
    padding-left: 0; /* remove any left padding */
    margin-left: 0; /* remove any left margin */
    text-indent: -19px; /* adjust as much as needed */
}
li:before {
    content: '•\00a0\00a0\00a0';
    color: #000; /* bonus: you can customize the bullet color */
}

Edited to update based on OP's comment

ok, then just break it up into 2 divs nested together

ul  {background: blue; position:static;}
.therest {position:relative; width:100%}
.indent {float:left; }

<div class="therest">
<p>
Est tincidunt doming iis nobis nibh. Ullamcorper eorum elit lius me delenit. 
</p>
<hr />
<h3>Lorem</h3>
<div class="indent">
<ul>
<li>list element</li>
<li>list element</li>
<li>list element</li>
</ul> 
<div>
the rest now under the UL
</div>

try changing the ul li css to

ul {float:left; background: blue; }

---

Working inside an LMS without access to head of doc, found it easier to go with margin-right: 20px as an inline style for the image. Which I owe to this site.

---

try this:

li{
    margin-left:5px;
}

If you want them to go left, just put in a -##px value.

---

or you could do this:

 #content ul {
        background:none repeat scroll 0 0 #AACCDD;
        float:left;
        margin-right:10px;
        padding:10px;

and then remove all the styling from the li

---

How about this?

ul{float:left; clear:right}

---

width: 300px;
height: 30px;
margin-left: auto;
right: 10px;

margin-left: auto will cause the element itself to be right aligned. Set height and width of the element you want - in my it's a background image in a div inside

---

You could try also floating the ul to the left, and define an appropriate width for it, so that it floats next to the image.

Something a little like this jsfiddle?

---

I fixed it with

div.class-name ul {
  clear: both;
}

---

width: auto; overflow: hidden;

---

Add display:table; to ul:

ul{display:table;}
