i have a problem with some icon color displaying on Iphone. Here the html code :

<button type="submit" aria-label="Start Searching">
   <i className={`icon-search`} aria-hidden="true" />
</button>

The icon color is correctly displayed ( that to say dark gray ) on Android or any desktop ( including Safari ) but he is fully white on Iphone ( Iphone 8, IOS 15.1 )

Does any one have a solution ?

CodePudding user response：

I was investigating and version feature is deprecated in some browsers, maybe can be that:

See the compatibility table:

Extracted from: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/version#browser_compatibility

I recommend you to use and icon from: https://fontawesome.com/v5.15/icons?d=gallery&p=2

CodePudding user response：

As @A Haworth pointed out: it might be ralated to some css rule in your global css.

Browser specific default styles

Since your icon already contains a hard coded fill attribute, my suspicion is your icon is colored white due to a safari default button style.
You could try to disable default button styling by applying an appearance: none rule.

button {
  font-size: 2em;
  display: block;
  width: 100%;
}

button svg {
  display: inline-block;
  height: 1em;
}

.btn-default {
  appearance: none;
  background: #fff;
  border: 1px solid #000;
}

.btn-default-use {
  color: #666;
}

button svg {
  display: inline-block;
  width: 1em;
}

.svgAssetHiddden {
  position: absolute;
  width: 0;
  height: 0;
  overflow: hidden;
}

Eventually, it might also be related to a Dark mode setting overriding your original fill to ensure a sufficient contrast.
