You could even use min-width and max-width to limit how big or small the image can get!
percent width
Percent is a measurement unit relative to the containing block. It's great for images: here we make an image that is always 50% the width of its container. Try shrinking down the page to see what happens!
article img {
float: right;
width: 50%;
}You can use percent for layout, but this can require more work. In this example, the nav content starts to wrap in a displeasing way when the window is too narrow. It comes down to what works for your content.
nav {
float: left;
width: 25%;
}
section {
margin-left: 25%;
}<div class="container"><section> <section>
When this layout is too narrow, the nav gets squished. Worse, you can't use min-width on the nav to fix it, because the right column wouldn't respect it.
