My process

Built with

  • Semantic HTML5 markup
  • CSS custom properties
  • Flexbox
  • Mobile-first workflow
  • JavaScript

What I learned

  • Changing the color of an SVG image on hover was quite a challenge for me. After a peruse of some articles (links below) that challenge became somewhat of an inspiration. I discovered that the combination of CSS filter properties does the trick. Some examples: 
.delete:hover {
    filter: brightness(0);
}/*Makes the image completely dark (bold) on hover */

.close {
  filter: brightness(90); 
}/* Turn Black (original) to White color */

.close:hover {
  filter: invert(55%) sepia(100%) saturate(3.5) brightness(110%);
} /* To Orange on hover */

.arr:hover img {
  filter: invert(55%) sepia(100%) saturate(3.5);
} /* Orange on hover */

.thumb:hover {
  filter: opacity(1) drop-shadow(0 0 0 #fff) saturate(0.2) brightness(150%);
} /* Make thumbnail opaque/white */
/* The dropshadow is used to change the image's color to white */
/* Combinations & Value types, degree or percentage: */

.user-acc .cart:hover {
  filter: invert(27%) saturate(2878%) hue-rotate(346deg) brightness(104%) contrast(97%);

  filter: invert(200%) saturate(5000%) hue-rotate(360deg) brightness(6%) contrast(50%); 

  filter: brightness(60%);
}
  • I also learned that the :hover pseudo-class needs a pointing (graphical input) device, capable of distinguishing the actions pointing and selecting/activating. Usually on mobile devices with a touch interface you don’t have the former, only the latter. That said, :hover has a weird behaviour on mobile devices and is problematic on touchscreens. A workaround for this is: 
@media (hover: hover) and (pointer: fine) {
 button:hover {
   ...
   /* True for pointing devices, not touchscreens */
 }
}

Continued development

I am currently learning React, a JavaScript library. Building this project made me realize how quickly JavaScript can become messy and all over the place. And how React is great for complex projects like this one – for building reuseable components.

Useful resources

These are amazing articles which helped me finally understand CSS filter and changing the color of svg images. And also :hover behaviour on touchscreens. I’d recommend it to anyone still learning this concept.
