Css hover sometimes doesn't work on svg paths (3 answers)

Closed 3 years ago.

As you can see on gif below, :hover state does not work properly when I move the mouse cursor from bottom polygon to upper polygon:

[jsfiddle]

Tested in Chrome and Firefox - the result is the same.

How can I achieve SVG polygon turn :hover state on right after mouse cursor enters its borders?

回答1:

There is no fill to catch the pointer event so it fails.

A simple transparent fill corrects it.

polygon {
  stroke-width: 1;
  stroke: red;
  fill: transparent;
}
polygon:hover {
  fill: red;
}

<svg viewBox="0 0 999 799">
  <polygon points="445,161 345,174 500,10" />

  <polygon points="445,161 345,174 500,270" />
</svg>

As mentioned by Robert Longson

pointer-events: visible is the preferred and performant solution.

polygon {
  stroke-width: 1;
  stroke: red;
  fill: none;
  pointer-events: visible;
}
polygon:hover {
  fill: red;
}

<svg viewBox="0 0 999 799">
  <polygon points="445,161 345,174 500,10" />

  <polygon points="445,161 345,174 500,270" />
</svg>
