how to change svg color when button is hovered

Keywords: html css svg hover

Question: 

I'm trying to me make an SVG's color change when the button is hovered.

I tried using button:hover + svg, but that doesn't seem to work.

When I run the CSS, the SVG fills to white and it doesn't work when I hover over the button. The only way I see it working is if I don't set an initial fill to orange and let it be black.

What's going wrong?

.box-button {
  border: 1px solid orange;
  color: orange;
  padding: 15px 0px;
  text-align: center;
  margin: 5px 5px;
  width: 90%;
  font-size: 1.2rem;
}

.box-button:hover {
  background-color: orange;
  color: white;
}

.box-button:hover+.icon-svg {
  fill: white !important;
}

.icon-svg {
  fill: orange;
}

Answers: 

+ is the CSS sibling selector. .icon-svg is not a sibling of your button, it is a child.

Try .box-button:hover .icon-svg instead of .box-button:hover+.icon-svg.

.box-button {
  border: 1px solid orange;
  color: orange;
  padding: 15px 0px;
  text-align: center;
  margin: 5px 5px;
  width: 90%;
  font-size: 1.2rem;
}

.box-button:hover {
  background-color: orange;
  color: white;
}

.box-button:hover .icon-svg {
  fill: white !important;
}

.icon-svg {
  fill: orange;
}
