The answer to this question is somewhat complex and could just as well be a separate article. However, to simplify this topic, let’s just say that it is all about computing power. With HTML (PHP, CSS, etc.) based websites, crawlers can “see” the website’s content by analyzing the code.
Basically, what you see above is code “processed” by the browser.
To see how the source code looked like before rendering, you need to use the “View Page Source” option.
After doing so, you can quickly notice that all the content you saw on the page isn’t actually present within the code.
