How Can I Make Flexbox Work Consistently Across Browsers, Especially Internet Explorer 11?

Flexbox Compatibility Enigma in Internet Explorer 11

As you delve into the realm of CSS flexbox, the support landscape can be a bit unpredictable. While major browsers generally play along, Internet Explorer 11 (IE11) presents some unique challenges.

IE11 and the Sticky Footer Conundrum

The "Sticky Footer" example from "Solved by Flexbox" fails in IE11. One enigmatic solution is to sprinkle display:flex on the tag and width:100% on the tag. The logic behind this magic wand is rooted in IE11's non-standard default values for flex properties. While other browsers adhere to the draft spec's 0 1 auto, IE11 insists on 0 0 auto. By explicitly setting these values (e.g., flex: 1 0 0), you can coax IE11 into greater alignment.

Taming the Media Object in IE11

The "Media Object" example also poses a challenge for IE11. Unfortunately, no universally clean solution seems to exist. You may have some success with browser-specific hacks, such as:

@-moz-document url-prefix() {
  #flexible-content {
    flex: 1;
  }
}

This hack targets Mozilla and overrides the flex property, restoring the desired behavior. However, be aware that such hacks can have unintended consequences in other browsers.

Remember, flexbox is still evolving, and browser inconsistencies are part of the landscape. Fortunately, the situation is improving, and with a bit of patience and ingenuity, you can navigate these challenges and harness the power of flexbox in your web designs.
