CSS Apply gradient color to a png logo branding

Question

sorry if it has been already asked but I can't find the solution on how to apply a gradient color to a png logo. Here is the website i'm starting to work on: julienbraida.com.

White Logo is on top left. Client wants apply a gradient color on top of the branding logo and change the gradient color according to pages (to match the theme of the page).

I only was able to apply a color using a filter. But it's not a gradient color and I would need help to do that please.

I've done this:

.mobile-header-bar .mobile-branding img {
  filter: sepia(100%) hue-rotate(19deg) saturate(100%);
}

But no gradient ... Thanks in advance for your help!

Answer 1

Set your image as a background:

NOTE:

• filters apply to foreground elements, typically images.
• Gradients are backgrounds and are effectively "under" images.
• so if you want to apply a linear-gradient to an img you have to overlay the <img> with another element with a greater z-index

div {
  height: 100px;
  width: 150px;
  display: inline-block;
}

.bgImageOnly {
  background: url('https://picsum.photos/id/1/200/300') no-repeat;
}

.bgImgFilter {
  filter: sepia(100%) hue-rotate(19deg) saturate(100%);
  background: url('https://picsum.photos/id/1/200/300') no-repeat;
}

.bgImgGradient {
  background: linear-gradient(135deg, rgba(255, 121, 0, .5) 0%, rgba(250, 0, 255, .5) 54%, rgba(126, 0, 255, .5) 100%), url('https://picsum.photos/id/1/200/300') no-repeat;
  ;
}



div.logos{
  width: 100%;
  overflow:hidden;
}

div.logos img{
  height: 80px;
  width: 150px;
}


img{
  padding: 20px 0px; 
}
.yourFilterParameters{
  filter: brightness(1) invert(0) drop-shadow(0 1px 1px rgba(41, 55, 90, .4));
}

.somethingMoreVisible {
  filter: brightness(70%) invert(30%) drop-shadow(4px 2px 2px rgba(255, 0, 0, 0.75))
}

div.gradientOverlay{
  height: 80px;
  width: 150px;
  position:relative;
  z-index:0;
}

div.gradientOverlay::after{
  content:"";
  position:absolute;
  top:20px;
  left:0px;
  z-index: 1000;
  height: 80px;
  width: 150px;
  background-image: linear-gradient(135deg, rgba(255, 121, 0, .5) 0%, rgba(250, 0, 255, .5) 54%, rgba(126, 0, 255, .5) 100%);
  
}

<div class="bgImageOnly"></div>
<div class="bgImgFilter"></div>
<div class="bgImgGradient"></div>
<hr>
<div class="logos">
  <img src="https://picsum.photos/id/1/200/300"
       class="yourFilterParameters">
  <img src="https://picsum.photos/id/1/200/300"
       class="somethingMoreVisible">
  <div class="gradientOverlay">
    <img src="https://picsum.photos/id/1/200/300">
