Find the logo.png file in the img folder. You may notice that its dimensions are large, 900px wide. In our final design, it will be only 120px wide. Because the pixels will be compressed into a smaller space, this is a relatively easy way to ensure that the image will look good in all devices, including retina displays. Meanwhile, the file size of the image, which has already been optimized for the Web, is only 19 KB.
So, let's put it in place and constrain its width.
Open
index.htmlin your editor.Search for this line within the navbar markup:
<a class="navbar-brand" href="index.html">Bootstrappin'</a>
Replace
Bootstrappin'with this image tag, including itsaltandwidthattributes.<img src="img/logo.png" alt="Bootstrappin'" width="120">
Save
index.htmland refresh your browser. You should see the logo in place.
