dynamic resizing, uniform dimensions

Is it possible to use CSS to ensure that an image is 100% the width of a fluid div without distorting the square shape? The goal is to match the height to the width for a cohesive look. Currently, I am using the following code for fluid width:

.img{
  max-width: 100%;
  width: 100%;
  min-width: 400px;
}

While this successfully sets the width in most major browsers, I'm struggling to figure out how to match the height to the width. Any suggestions would be appreciated!

Answer №1

Consider adding height:auto to your CSS class.

.img{
  max-width: 100%;
  width: 100%;
  min-width: 400px;
  height: auto; // <-- don't forget me
}

It's worth noting that most browsers should handle image scaling correctly, but this addition may be beneficial in some cases. Thank you for the input!

Answer №2

With the introduction of CSS3, new units have emerged that are relative to the viewport (browser window). For a fluid image that adjusts well according to the size of the window, using vh and vw can be more effective than using "%". The vh unit measures viewport height while the vw unit measures viewport width.

.img{
  max-width: 100vw;
  width: 100vw;
  min-width: 400px;
  height: auto;
}
