text-decoration-thickness
The text-decoration-thickness CSS property sets the stroke thickness of the decoration line that is used on text in an element, such as a line-through, underline, or overline.
Syntax
/* Single keyword */ text-decoration-thickness: auto; text-decoration-thickness: from-font; /* length */ text-decoration-thickness: 0.1em; text-decoration-thickness: 3px; /* percentage */ text-decoration-thickness: 10%; /* Global values */ text-decoration-thickness: inherit; text-decoration-thickness: initial; text-decoration-thickness: revert; text-decoration-thickness: unset; Values
auto The browser chooses an appropriate width for the text decoration line.
from-font If the font file includes information about a preferred thickness, use that value. If the font file doesn't include this information, behave as if auto was set, with the browser choosing an appropriate thickness.
<length> Specifies the thickness of the text decoration line as a <length>, overriding the font file suggestion or the browser default.
<percentage> Specifies the thickness of the text decoration line as a <percentage> of 1em in the current font. A percentage inherits as a relative value, and so therefore scales with changes in the font. The browser must use a minimum of 1 device pixel. For a given application of this property, the thickness is constant across the whole box it is applied to, even if there are child elements with a different font size.

"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.
