u cant change the opacity of a svg but what u can do is change the opacity of the parent element and you will have the same effect

https://jsfiddle.net/6ncydmhw/1/

<div class="change-opacity-svg">
<svg id="Capa_1" data-name="Capa 1" height="40" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 61.2 60.64"><defs></defs><title>google+</title><path class="google-plus-1" d="M30.6,2.45A27.92,27.92,0,1,0,58.52,30.37,27.92,27.92,0,0,0,30.6,2.45ZM33.22,37.9c-3.24,4.56-9.74,5.89-14.81,3.93a13,13,0,0,1,4.72-25.16,13.2,13.2,0,0,1,8.7,3.21,46.8,46.8,0,0,1-3.3,3.42c-3-2-7.17-2.63-10.13-.27A8.33,8.33,0,0,0,18,36c4,3.59,11.44,1.81,12.54-3.69-2.48,0-5,0-7.45-.08,0-1.48,0-3,0-4.44,4.15,0,8.29,0,12.45,0C35.82,31.31,35.36,35,33.22,37.9Zm14.33-4.76v3h-  4v-3h-3v-4h3v-3h4v3h3v4h-3Z"/></svg>
</div>



.google-plus-1{
fill:#dc4e41;
}
.change-opacity-svg:hover{
opacity:0.6;
}

Solution 2

CSS does not work over file boundaries. Any CSS in your HTML will not affect the SVG. It's just the same as if you were including another HTML page using an iframe. CSS in the parent would have no affect on the iframed page.

What you can do to get around this is use a little script to replace your tags with embedded SVG. See:

i have a problem with my css.

this is my html:

<nav id="navigation">
    <ul>
        <li>
            <a class="navbtn" href="?page=contact">
            <img src="images\navigation\icons\contact.svg" width="25px">
                <p>contact</p>      
            </a>
        </li>
    </ul>
</nav>

this is my css:

#navigation ul:nth-child(1) li a:hover {
text-shadow: 0px 0px 20px black;
opacity: 1.0;

}

.iconopacity {
    fill-opacity: 0.3;
}

.iconopacity:hover {
    pointer-events: all;
    fill-opacity: 0.7 !important;
}

this is my svg file:

I made the icon with illustrator. I want to make the icon a little bit darker, by decreasing the transparancy when the mouse hovers over the icon. I tried it with:

.iconopacity:hover {
     fill-opacity: 0.7; 
}

but it didn't work. i also tried it with a bunch of other css selectors like:

  #navigation ul:nth-child(1) li a:hover .iconopacity { css here }

but it didn't work either.

I think i'm selecting the path wrong with my css while hovering over the link, but the problem could also be something entirely different.

I think the problem could also be solved by using javascript, but i'm not in to javascript, and i think it should be possible to do with css.

please help me? :)

Is this also if i have a separate css file? i have placed at the top of the svg file this line: <?xml-stylesheet type="text/css" href="localhost/project0/html/css/stylesheet.css" ?>, indicating that the stylesheet also applies to the svg.

a) images must be complete in a single file. b) images are not interactive. You need to use an <iframe> or <object> tag or inline the svg image if you want it to be interactive.
