When we want to convey importance, seriousness, or urgency, which element do we use? You can verify these claims by comparing your previous experience with a more modern website structure example, which could look something like this: If you try our more modern structure example with a screen reader, you'll see that the layout markup no longer gets in the way and confuses the content readout. When in doubt, try to match the behavior of actual browsers. But then I did a web diff and I saw that there are subtle differences in the text. ), you need to be able to find your domain's authoritative nameserver and query it to see what records it has.
