Is there a way to eliminate the gap between these elements?

Hey there, I'm currently working on a web project using Bootstrap 3.3.7

Check out this snippet of my HTML code:

<nav class="navbar navbar-default nobottommargin" role="navigation">
    <div class="container-fluid">

        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-9">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="#">Brand</a>
        </div>

        <div class="collapse navbar-collapse" id="">
            <ul class="nav navbar-nav">
                <li class="active"><a href="#">Home</a></li>
                <li><a href="#">Link</a></li>
                <li><a href="#">Link</a></li>
            </ul>
        </div>

    </div>
</nav>

<iframe src="https://www.news.sky.com" style="width:100%;height:100%" frameborder="3"></iframe>

Take a look at the JSFiddle for a live demo.

In the example above, you'll notice some space between the navbar and the iframe. How can I eliminate this space and move the iframe closer to the navbar?

Answer №1

In the code snippet above, the class .navbar has a margin of 20px at the bottom. To override this default style, you can create your own CSS class:

.nobottommargin {
  margin-bottom: 0;
}

Answer №2

Modifying default bootstrap styles is not recommended, even when using !important.

To address this issue, simply adjust the margin-top of the iframe by setting it to a negative value:

iframe {
   margin-top: -20px;
}

Answer №3

Include the following:

.navigation-bar {
    padding-top: 10px;
}

Answer №4

Make sure to adjust the bottom margin for the nav tag in order to achieve the desired styling:

<nav class="navbar navbar-default nobottommargin" role="navigation" style="margin-bottom: 0px">

Answer №5

You've made a modification in your fiddle by including the nobottommargin class to your navbar. By adding custom CSS to your HTML as illustrated below, you will notice that the margin vanishes.

.nobottommargin {
    margin-bottom: 0px;
}
