Here is what I'm trying to achieve:

Is there a way to do this with a W3 web technology, e.g. SVG, Canvas?
Yes, you can, by using the text-fill-color and background-clip properties.
html, body {
  background: #000;
}
p {
  margin: 0px;
}
#clip {
  background: linear-gradient(to right, rgba(127, 127, 127, 1) 23%, rgba(234, 85, 7, 1) 20%, rgba(234, 85, 7, 1) 57%, rgba(127, 127, 127, 1) 59%);
  background-attachment: fixed;
  -webkit-text-fill-color: transparent;
  -webkit-background-clip: text;
  font-size: 8vw;
  font-weight: bold;
  text-align: center;
}<p id="clip">Lorem ipsum dolor sit </p>NOTE: Visit this link for more information.
