Actually you can just highlight the URL and right click, you get an option to open it in various ways... (firefox and chrome)
I do not have any "Open" options on my right-click from "Show Source". From "Show Source" once I've highlighted the url, the only right-click options available are "Find Again", "Copy" (which I'm already doing, albeit from a keyboard shortcut), and "Select All".
If I try it from "Inspect Elements", I can expand the head tag, double-click to select the comment, click and drag to select the url, at which point my right-click only has the "Show DOM Properties" option available. But this has already taken longer than the above show source, then copy-paste, and go.
Turns out I was able to highlight and right click because I was selecting the <pre> embedded text in the comments of hacker news, rather than viewing source on the waterstones link.
I'm dismayed to report that the view source window doesn't give you this open. Even worse, if you right click on something that's highlighted as being a URL you can't even open it in a new window/tab. Colour me disappointed.
Whether or not they'd be interested in reading a book when you can just watch it on Youtube is another matter entirely!
Key word in my original statement - "probably". I didn't claim that everyone reading it was beyond needing a beginners book, just that a reader of the code was "probably" ready for books beyond "HTML & CSS".
As for books versus Youtube - yep, I'm an immigrant. In most cases, I personally still prefer books, online tutorials, and online forums to Youtube. But I'm not surprised to hear that isn't the case with kids. But then again, we're discussion a book-seller's site.
Is it even possible to have clickable hyperlinks in HTML comments?
echo `curl https://www.waterstones.com/` | grep -o 'http[^ "]/book/[^ "]' | xargs open -a Google\ Chrome
2. If someone is looking in the code, they're probably ready for books beyond "HTML & CSS".
3. The urls aren't hyperlinked, so readers have to copy-paste.
4. The two books I bothered to copy-paste both report, "Not in our warehouse". One of them further reports that "We can order it, but could take up to 3 weeks". The big-A can have it to me in 3 days, two of which are the weekend.
