background-clip
The background-clip CSS property sets whether an element's background extends underneath its border box, padding box, or content box.
If the element has no background-image or background-color, this property will only have a visual effect when the border has transparent regions or partially opaque regions (due to border-style or border-image); otherwise, the border masks the difference.
Note: Because the root element has a different background painting area, the background-clip property has no effect when specified on it. See "The backgrounds of special elements."
Note: For documents whose root element is an HTML element: if the computed value of background-image on the root element is none and its background-color is transparent, user agents must instead propagate the computed values of the background properties from that element's first HTML <body> child element. The used values of that <body> element's background properties are their initial values, and the propagated values are treated as if they were specified on the root element. It is recommended that authors of HTML documents specify the canvas background for the <body> element rather than the HTML element.
Syntax
/* Keyword values */ background-clip: border-box; background-clip: padding-box; background-clip: content-box; background-clip: text; /* Global values */ background-clip: inherit; background-clip: initial; background-clip: revert; background-clip: unset; Values
border-box The background extends to the outside edge of the border (but underneath the border in z-ordering).
padding-box The background extends to the outside edge of the padding. No background is drawn beneath the border.
content-box The background is painted within (clipped to) the content box.
text The background is painted within (clipped to) the foreground text.
Accessibility concerns
When using background-clip: text check that the contrast ratio between the background color and the color of the text placed over it is high enough that people experiencing low vision conditions will be able to read the content of the page.
If the background image does not load, this could also lead to the text becoming unreadable. Add a fallback background-color to prevent this from happening, and test without the image.
Consider using feature queries with @supports to test for support of background-clip: text and provide an accessible alternative where it is not supported.

"Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything. 'Are you feeling all right?' I asked her. 'I feel all sleepy,' she said. In an hour, she was unconscious. In twelve hours she was dead. The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her. That was...in 1962, but even now, if a child with measles happens to develop the same deadly reaction from measles as Olivia did, there would still be nothing the doctors could do to help her. On the other hand, there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunised against measles. ...I dedicated two of my books to Olivia, the first was ‘James and the Giant Peach’. That was when she was still alive. The second was ‘The BFG’, dedicated to her memory after she had died from measles. You will see her name at the beginning of each of these books. And I know how happy she would be if only she could know that her death had helped to save a good deal of illness and death among other children."
I just checked google books for BFG, and the dedication is there.
