How to Delete Code Below the Footer Section

I’m hoping you can give me some advice:

I created a blog post you can see here: https://www.reyrrodriguez.com/seo-services-worth-it/

I added videos by embedding the YouTube player. I realized the page became a lot slower. So I tried to fix it by following this tutorial. https://www.labnol.org/internet/light-youtube-embeds/27941/

I added the script part using google tag manager using custom HTML tag: http://prntscr.com/py9xk7

Then I added the css under themes, customize, additional css: http://prntscr.com/py9yve

The problem is, as you can see near the bottom of the page under the footer the code shows: http://prntscr.com/py9zic

I tried to run a system backup using siteground which is my hosting service. But it did not work to revert the change.

Can you give me some tips how I can complete this correctly: https://www.labnol.org/internet/light-youtube-embeds/27941/

And remove the code at the bottom?

I would really appreciate. -Rey

PS: Before completing the system back up I paused the tag within tag manager and also tried to delete it. But the code at the bottom never went away.

What constitutes a minimal-sum section of an integer array

I’m having trouble understanding what constitutes a “minimal sum section” of an integer array. My book defines it as the following:

Let $ a[0],\dots, a[n-1]$ be the integer values of an array $ a$ .
A section of $ a$ is a continuous piece $ a[i],\dots,a[j]$ , where $ 0\le i \le j < n$ . We write $ S_i,_j$ for the sum of that section: $ a[i] + a[i+1]+\dots+a[j]$ .
A minimal-sum section is a section $ a[i],\dots,a[j]$ of $ a$ such that the sum $ S_{i,j}$ is less than or equal to the sum $ S_{i’,j’}$ of any other section $ a[i’],\dots,a[j’]$ of $ a$ .

My confusion comes with one of the examples that follow this definition:

The array [1,-1,3,-1,1] has two minimal-sum sections [1,-1] and [-1,1] with minimal sum 0.

But, wouldn’t the minimal sum section be $ [-1]$ ?

In a later example they give:

array $ [-1,3,-2]$

Minimal sum

section $ [-2]$

So, in the last example they definitely counted one element as the minimal sum section, but not in the first one. Any clarification on why this is so would be greatly appreciated.

Any thought framework to decide between section vs page?

Are there any patterns one should follow to help them decide if a topic should should go as a separate page on a website or should it be a section under an existing page?

e.g: For my SaaS @ https://divshow.bytebeacon.com .. When you login .. I have a bunch of things shoved under the “Accounts” page. There are profile details in there, basic stats and billing. I feel like I should separate out Billing section into a separate page (it seems like a high value page), but I can keep profile info and basic stats together. I can also split “Stats” in its own page, but now I’m starting to feel there might be too many pages (I wanted to keep low number of clicks for the user as well).

How do you think about a topic getting its own page vs being placed as a section in another page? Also what would your advice be on my “Accounts” page?

Is it confusing to link to another section of a site for more info?

I want to create a portfolio site for my team. I have two goals: 1. Create a section to showcase our projects 2. Have a blog where we can provide updates and talk about the “behind the scenes” of our projects.

Here is my question:
If someone lands in the project section and sees a project, would it be confusing to also have articles in the blog talking about the same project? Is that redundant? Would a user expect to see ALL information for a project in one place?

Or…am I doing too much with the blog? Should blogs on sites like this be reserved for updates only?

Setting a shortcut to change focus to a different section in a web app?

Let’s say you have a web app with 3 sections. A left nav menu, a toolbar/settings section, and a main application area. Most of the time, the user will be engaging directly with the application, and their document’s focus will be potentially somewhere deep inside of the application’s “hierarchy”, meaning that tabbing into/out of the application to place focus on the left nav or toolbar will be a pain.

Is adding a shortcut (and making the shortcut’s keystrokes visible next to that section maybe?) to change focus to the left navigation menu or the toolbar a good idea generally? Otherwise they may have to do a lot of tabbing or use some other method of interacting with that part of the site, which we’d like to avoid. Bonus points if anyone knows how this aligns with WCAG a11y requirements.
