enigmatic margin surrounding navigation dots

I have added a straightforward dot navigation to the banner of my website. You can check it out HERE. The HTML code I used is shown below:

<ul class="carousel-dots">
    <li>
        <a href=""></a>
    </li>
    <li>
        <a href=""></a>
    </li>
    <li class="active">
        <a href=""></a>
    </li>
</ul>

For the <li> element, I have the following CSS code:

.banner ul.carousel-dots li {
    height: 13px;
    width: 13px;
    display: inline-block;
    background: url(../img/res/carousel-dots.png) 0 0 no-repeat;
    margin: 0;
    cursor: pointer;
}

Despite having margin: 0; in my style, there seems to be a mysterious margin between the dots. I'm not sure where these spaces are coming from as I want the dots to touch each other directly. What could be causing this unexpected margin?

Answer №1

Dealing with white space between inline-block elements

If you're wondering about the annoying white space that appears between your inline-block elements, it's actually caused by the "enter" or line break in your HTML code.

Here's a helpful resource on how to remove the space between inline-block elements

In the discussion linked above, there are various suggestions on how to tackle this issue.
One common approach is setting the parent element's font-size to 0 to eliminate the whitespace.

ul {
  font-size: 0;
}
ul.carousel-dots li {
  height: 13px;
  width: 13px;
  display: inline-block;
  /*background: url(../img/res/carousel-dots.png) 0 0 no-repeat;*/
  background-color: black;
  border-radius: 50%;
  margin: 0;
  cursor: pointer;
}
<ul class="carousel-dots">
  <li>
    <a href=""></a>
  </li>
  <li>
    <a href=""></a>
  </li>
  <li class="active">
    <a href=""></a>
  </li>
</ul>

Answer №2

Alright, here's a little trick to fix the issue at hand. To remove the space between </li> and the following <li>, simply eliminate the line break.

For instance, instead of:

<ul class="carousel-dots">
<li>
    <a href=""></a>
</li>
<li>
    <a href=""></a>
</li>
<li class="active">
    <a href=""></a>
</li>

Your code should look like this:

<ul class="carousel-dots">
<li>
    <a href=""></a>
</li><li>
    <a href=""></a>
</li><li class="active">
    <a href=""></a>
</li>

This issue arises because spaces are treated as inline characters when using inline-block elements.

PS: While there are other methods to address this spacing problem, I believe keeping it simple is key. Additionally, minimizing your code before deployment is essential in HTML, so opting for fewer lines of code is always preferable.
