Responsive Separator For Horizontal List

Responsive Separator for Horizontal List

You can exploit fact that trailing and line trailing white space automatically collapses:

document.write(
 'word<b style="background: red; outline: 1px solid blue;"> </b>'
 .repeat(42)
);

How to style a horizontal list with bullets between items using CSS?

Here is a further improved version. I kept getting an inconsistency at certain page widths where two bullets would be missing rather than just the last one. i.e.

link1 · link2 · link3 link4

link5 · link6

I think the issue was that removing the last bullet separator could itself affect the text flow if the page width was just right. The new script locks the original text flow by adding and removing literal line breaks.

I have the same script to run every time the screen is resized so you don't get stuck with awkward line breaks.

<style>
ul { width: 700px; text-align : center }
ul li { display: inline; white-space: nowrap; }
ul li:after { content: " \00b7"; }
ul li.nobullet:after { content: none; }
</style>

<body onresize="processBullets()" onload="processBullets()">
<ul>
    <li><a href="http://google.com">Harvard Medical School</a></li>
    <li><a href="http://google.com">Harvard College</a></li>
    <li><a href="http://google.com">Harvard Medical School</a></li>
    <li><a href="http://google.com">Harvard College</a></li>
    <li><a href="http://google.com">Harvard Medical School</a></li>
    <li><a href="http://google.com">Harvard College</a></li>
    <li><a href="http://google.com">Harvard Medical School</a></li>
    <li><a href="http://google.com">Harvard College</a></li>
</ul>
<body>

<script>
function processBullets() {
    var lastElement = false;
    $("br").remove(".tempbreak");
    $("ul li").each(function() {
        $(this).removeClass("nobullet");
        if (lastElement && lastElement.offset().top != $(this).offset().top) {
            $(lastElement).addClass("nobullet");
            $(lastElement).append('<br class="tempbreak" />');
        }
        lastElement = $(this);
    }).last().addClass("nobullet");
}

</script>

css responsiveness from vertical to horizontal divider when shrink the window

Use a CSS border. In mobile, make it a top or bottom border (so it is horizontal), and on desktop make it a left or right border (so it is vertical) with a @media query.

Add a pipe separator after items in an unordered list unless that item is the last on a line

This is possible with `flex-box`

The keys to this technique:

A container element set to overflow: hidden.
Set justify-content: space-between on the ul (which is a flex-box) to force its flex-items to stretch to the left and right edges.
Set margin-left: -1px on the ul to cause its left edge to overflow the container.
Set border-left: 1px on the li flex-items.

The container acts as a mask hiding the borders of any flex-items touching its left edge.

.flex-list {
    position: relative;
    margin: 1em;
    overflow: hidden;
}
.flex-list ul {
    display: flex;
    flex-direction: row;
    flex-wrap: wrap;
    justify-content: space-between;
    margin-left: -1px;
}
.flex-list li {
    flex-grow: 1;
    flex-basis: auto;
    margin: .25em 0;
    padding: 0 1em;
    text-align: center;
    border-left: 1px solid #ccc;
    background-color: #fff;
}

<div class="flex-list">
    <ul>
        <li>Dogs</li>
        <li>Cats</li>
        <li>Lions</li>
        <li>Tigers</li>
        <li>Zebras</li>
        <li>Giraffes</li>
        <li>Bears</li>
        <li>Hippopotamuses</li>
        <li>Antelopes</li>
        <li>Unicorns</li>
        <li>Seagulls</li>
    </ul>
</div>

Separators for Navigation

Simply use the separator image as a background image on the li.

To get it to only appear in between list items, position the image to the left of the li, but not on the first one.

For example:

#nav li + li {
    background:url('seperator.gif') no-repeat top left;
    padding-left: 10px
}

This CSS adds the image to every list item that follows another list item - in other words all of them but the first.

NB. Be aware the adjacent selector (li + li) doesn't work in IE6, so you will have to just add the background image to the conventional li (with a conditional stylesheet) and perhaps apply a negative margin to one of the edges.

Does bootstrap 4 have a built in horizontal divider?

HTML already has a built-in horizontal divider called <hr/> (short for "horizontal rule"). Bootstrap styles it like this:

hr {
  margin-top: 1rem;
  margin-bottom: 1rem;
  border: 0;
  border-top: 1px solid rgba(0, 0, 0, 0.1);
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />
<p>
   Some text
   <hr/>
   More text
</p>
