This question expands upon 'Separators For Navigation' by asking, how it is possible to remove the separators at the line breaks cause by viewport size.
Wide Viewport-> Item 1 | Item 2 | Item 3 | Item 4 | Item 5 <-
Small Viewport
-> Item 1 | Item 2 | Item 3 <-
-> Item 4 | Item 5 <-
Here is a fiddle that shows how a pipe remains at the line break:
Fiddle.
I'm interested in a css-only solution, but javascript is acceptable if it provides the only possible solution.
The <hr> tag defines a thematic break in an HTML page (e.g. a shift of topic). The <hr> element is most often displayed as a horizontal rule that is used to separate content (or define a change) in an HTML page.
Adding the Horizontal Line using <hr> tag: The Horizontal Rule tag (<hr>) is used for the purpose of inserting horizontal lines in the HTML document in order to separate sections of the document. It is an empty or unpaired tag that means there is no need for the closing tag.
The HTML <hr> tag is used to create a horizontal line with the purpose of dividing sections of a page.
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)
);
As you can see there are red spaces with blue outlines between words, but the very last and and two at line ends lack the red area because it's width collapsed to zero: that is the white-space collapsing in effect.
It is possible to adjust width with word-spacing
and use pseudo element instead, so setting inline ::after { content: ' '; word-spacing: 2em; }
gives you wide inline rectangle that can have decorated backgrounds or borders but disappears when it is not between words.
Simplified use case (from https://codepen.io/myf/pen/dyOzpZM, tested just in 2021-02 evergreen Firefox and Chromium, will not work in pre-Chromium Edge; for more robust example see the second snippet below):
ul {
text-align: center;
padding: 0;
}
li {
display: inline;
}
li::after {
/*
This has to be space, tab or other
breakable white-space character:
*/
content: " ";
word-spacing: 1em;
background-image: linear-gradient(
-0.2turn,
transparent 0 calc(50% - 0.03em),
currentcolor 0 calc(50% + 0.03em),
transparent 0
);
}
/*
That's it: just inline text
with styled ::after spaces
that collapse at line breaks
and at the end of the element.
That's basically how spaces work in text.
*/
/*

body { background: #456; color: #fed; min-height: 100vh; margin: 0; display: flex; align-items: center; }
ul { --dur: 3s; font-family: Georgia, serif; font-size: min(7vw, calc(100vh / 7)); margin: 0 auto; position: relative; padding: 0 1em; -webkit-text-fill-color: #999; text-transform: capitalize; animation: poing var(--dur) infinite alternate ease-in-out; }
@keyframes poing { from { max-width: 3.4em; } to { max-width: min(19em, calc(100vw - 2em)); color: lime; } }
ul::before, ul::after { -webkit-text-fill-color: currentcolor; position: absolute; top: 50%; transform: translatey(-50%); animation: calc(var(--dur) * 2) calc(var(--dur) * -1.5) infinite forwards linear; }
ul::before { content: "☜"; left: 0; animation-name: a !important; }
ul::after { content: "☞"; right: 0; animation-name: b !important; }
@keyframes a { 50% { content: "☛"; } }
@keyframes b { 50% { content: "☚"; } }
ul:hover, ul:hover::before, ul:hover::after { animation-play-state: paused; }
<ul>
<li>foo</li>
<li>bar</li>
<li>baz</li>
<li>gazonk</li>

It uses flat list with single word items, so is not very relevant for real-world usage. More realistic variation suitable for navigation could be something like https://jsfiddle.net/vnudrsh6/7/ :
nav {
text-align: center;
padding-right: 1em; /* = li::after@word-spacing */
}
ul {
display: inline;
margin: 0;
padding: 0;
}
li {
display: inline;
/*
white-space: nowrap should be moved to child A
because IE fails to wrap resulting list completely
*/
}
li::before {
content: ' ';
/*
this content is important only for Chrome in case
the HTML will be minified with *no whitespaces* between </li><li>
*/
}
li::after {
content: ' ';
/*
this is actual placeholder for background-image
and it really must be space (or tab)
*/
white-space: normal;
word-spacing: 1em;
/*
= nav@padding-right - this actually makes width
*/
background-image: radial-gradient(circle, black, black 7%, transparent 15%, transparent 35%, black 45%, black 48%, transparent 55%);
background-size: 1em 1em;
background-repeat: no-repeat;
background-position: center center;
opacity: 0.5;
}
/*
no need to unset content of li:last-child::after
because last (trailing) space collapses anyway
*/
a {
white-space: nowrap;
display: inline-block; /* for padding */
padding: 1em;
text-decoration: none;
color: black;
transition-property: background-color;
transition-duration: 500ms;
}
a:hover {
background-color: #ccc;
}
/*

outline: 3px dotted rgba(0,0,255,.5);

opacity: 1;
background-color: rgba(255, 0, 0, .5);

This proof-of-concept uses background-image of "eventually colapsing" CSS generated content space after each <li>
. Tested in 2016 in Firefox, Chrome and IE11.
