QUESTION
im starting to learn web scraping in javascript with puppeteer. I found a video that I liked that showcases puppeteer and I'm trying to scrape the same information as the video(link). the page has changed a little from the video so I used what I think are the correct tags.
the problem comes when I try to find the "h3"
tag. the tag exists in the DOM but my code refuses to acknowledge its existence but works "fine" when looking for the "h2"
tag.
what I want to know is why my code does not retrieve it.

QUESTION
I'm trying to learn how to animate with CSS in a DevTips Tutorial but had to stop about 8-minutes in since my code isn't animating the menu items properly. They simply pop into place, but are supposed to flip and fade in simultaneously.
I hope it isn't taboo to post something that's been written at CodePen; my sincerest apologies if it is. If it's kosher, CLICK HERE.
As far as I can tell, my code matches exactly what's in the tutorial, so I was hoping someone could spot whatever error I'm overlooking.
Achtung!! My codepen syntax is using Pug and SASS preprocessors, so if you don't like looking at that kind of syntax, the compiled HTML and CSS is included below.
Many thanks in advance.
HTML ::
...ANSWER
Answered 2017-Feb-09 at 05:10Looks like you have a very simple problem with your Pug processing in this line:
ul(class="drop-menu menu-#{i}")
This isn't adding the class "menu-1" through "menu-4" as expected. To fix this write the Pug statement like this instead:
ul(class="drop-menu menu-" + i)
This is the new syntax that Pug specifies using, you can read more here.

Install devTips
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
