I'm trying to draw a horizontal line between empty circles (no background), How can I draw a line from one circle to other to match exactly without entering the other circle or not reach it?
I did the sample using codepen
#wizard { background-color: #eee; display: inline-block; padding: 15px; } #wizard .step { display: inline-block; width: 40px; height: 40px; background-color: transparent; border: 1px solid #000; border-radius: 50%; text-align: center; padding: 2px; margin-right: 3em; margin-left: 3em; position: relative; } #wizard .step:after { content: ""; display: block; height: 1px; background-color: #000; position: absolute; left: auto; right: -100%; width: 100%; top: 50%; } #wizard .step:last-child:after { display: none; } #wizard .step span { padding: 11px; display: block; }
<div id="wizard"> <div class="step active"> <span>1</span> </div> <div class="step"> <span>2</span> </div> <div class="step"> <span>3</span> </div> </div>
Since your margin-right
and margin-left
are both 3em
, try using 6em
instead of 100%
left:auto;
right:-6em;
width:6em;
That leaves a little space, but you can tweak it:
right:-6.3em;
width:6.3em;
If you're going to absolutely position your #wizard .step::after
pseudo-element, you need to know 2 things:
You can see where it should begin, given that your #wizard .step
has a border of 1px
, a padding of 2px
and a content width of 40px
.
1px
+ 2px
+ 40px
+ 2px
+ 1px
= 46px
So your position styles need to include left: 46px
:
#wizard .step::after {
position: absolute;
top: 50%;
left: 46px;
}
As for how long it needs to be, it needs to span the margin-right
of the current #wizard .step
and then the margin-left
of the next #wizard .step
.
Since these are both 3em
, you can give it your #wizard .step::after
pseudo-element a width
of 6em
.
Putting it all together:
#wizard { background-color: #eee; display:inline-block; padding:15px; } #wizard .step { display: inline-block; width: 40px; height: 40px; background-color: transparent; border: 1px solid #000; border-radius: 50%; text-align: center; padding: 2px; margin-right: 3em; margin-left: 3em; position: relative; } #wizard .step::after { content: ''; display: block; position: absolute; top: 50%; left: 46px; width: 6em; height: 1px; background-color: #000; } #wizard .step:last-child::after { display:none; } #wizard .step span { padding: 11px; display: block; }
<div id="wizard"> <div class="step active"> <span>1</span> </div> <div class="step"> <span>2</span> </div> <div class="step"> <span>3</span> </div> </div>
NB It's really not clear to me why, but though the result from the approach above should be flawless, the actual result includes tiny gaps - giving every impression of being from a 1950s text-book.
If you want to eliminate these gaps, use the following style declarations, instead:
#wizard .step::after {
left: 45px;
width: 6.3em;
}
