Hi Kirupa members,
Could you please help.
Is it possible to change on hover this black color inside the icon with CSS ?
I can change the black color inside the path. But it doesn’t work for hover effect.

Hi @Helena_G - you can do this by using a CSS custom property! Take a look at the full code here:

    }

    .icon {
      fill: yellow;
      stroke: black;
      transition: all 0.5s ease-in-out;

      --youtubeColor: #090B0C;

  <div class="icon-container">

        <use href="#youtube"></use>
      </svg>

    </div>
  </div>

I defined a CSS property called youtubeColor that I assigned to the SVG path as well. On hover, I change the value of that color to whatever I would like it to be:

.icon {
  fill: yellow;
  stroke: black;
  transition: all 0.5s ease-in-out;

  --youtubeColor: #090B0C;
}


.icon:hover {
  fill: yellowgreen;
  --youtubeColor: red;
}

Does this work for you?

Cheers,

@Helena_G - to provide another approach, you can target the SVG color attribute using CSS as shown in this quick YouTube short I recorded a few minutes ago:

Lastly, a full video on how to change an element’s SVG color using both CSS and JavaScript techniques!

Using SVG source code in your DOM is unpractical from several reasons in terms of performance.

I would suggest to work with svg in old-fashion way, by <img src="image.src" />.
You can modify color of whole css by mask rule:

Example:

.your-image {
  mask: url("image.svg") no-repeat center;
}

.your-image:hover {
  background: red;
}

For some browsers is good to add autoprefixer because they had some issues with mask.

Hi @landsman - welcome to the forums! :slight_smile:

From my understanding, your approach doesn’t work for changing only a single color (or a subset of colors) from a multi-colored SVG. Do I have it right?

With that said, I should add a note to explain that having a lot of inline SVGs isn’t very performant. This is especially true if they have a lot of DOM nodes. I do run all of my SVGs through SVGOMG to reduce their complexity and size, but…it isn’t perfect.
