Whew, I got out of the computer support biz just in time. First crowdstrike, now this.
All we ever had to deal with was the old intel floating point debacle.

Intel can't afford to recall all of the chips it has produced in the last 2 years. OTOH, not recalling the chips gives them an incredible image problem.
I have bought Intel CPUs for the last 45 years (going back to my first IBM "portable" PC). It is likely that my next PC (or portable) will have an AMD chip.

Luckily the Dell Inspiron 16 notebook that I recently bought (for a ridiculous low price) has an AMD Ryzen 5 processor. I'm pleased with it so far, although it does not have a dedicated graphics card I can even play Skyrim on it, the fans start blowing loudly after about 10 minutes though now it's summer

I have an AMD 5800x and an AMD 6900XT (almost three years old).
A VM, 3 Instances of "Lord of the rings" online, several browser tabs and 2 instances of Sketch up 2017 open.
Be Quiet case with 2x silent wings and a dark rock pro 4 for the CPU.
The fans only activate second speed from time to time for 10 or 15 seconds.
My first AMD components and, right now, I do not see me coming back to intel soon.

While working on a SPA I had some CSS that I was applying on the click of a button.
When the button was clicked, it would make one or the other DIVs go fullscreen (except for a small portion at the top where the nav bar was).
Imagine you have these two divs -- one yellow and one cyan;
#first{
background: yellow;
}
#second{
background: cyan;
}Then when you click a button in the navbar it would make one or the other go fullscreen by applying a fullscreen CSS class.
It worked great & I was very happy with the simplicity of it all.
If you really want to see it work (toggle), take a look at this simple jsfiddle[^].
.fullScreen{
width: 100%;
height: 90%;
z-index: 20;
position: absolute;
top: 12%;
padding: 10pt;
}Here's the button click code.
document.querySelector("#first").classList.add("fullScreen");
document.querySelector("#second").classList.remove("fullScreen");
It Worked, Then Didn't!
It was all working. I copied the code to another project and had it all set up.
But suddenly clicking the button wouldn't do the fullscreen. I tried all manner of things.
Was the button click working? I added an alert() and saw the button was working.
I was going out of my bleedin' mind.
Then I looked real hard at the styles that I had copied to the new project.
Can You See It?
Do you see the problem?
#first{
background: yellow;
}
#second{
background: cyan;
};
.fullScreen{
width: 100%;
height: 90%;
z-index: 20;
position: absolute;
top: 12%;
padding: 10pt;
}
Oy!! I have only myself to blame.

Don't see the reason for it off the top of my head. Absolute should work with a static parent. Usually when stuff is not shown and it's not a display issue (or no content) then it's related to height. As body height needs to be set as well, etc. So that would be my guess.
Couple points about your code though...
I urge you to consider never, ever doing that again though.  You don't need to hard code offsets, as that'll just make things harder to maintain. And, this day and age we should be using flexbox for layout. And yes that includes fullscreen dialogs. It'll keep things organized sooo much better and if you ever need to stack a dialog on top of your main content or stack multiple dialogs, then it'll make your life easier.
Also, never, ever use height 100% in that manner.  There are better ways now. That was the trick 20 years ago. These days it's much, much better to use viewport units for layout. Height 100% means 100% of the parent. That trick only only worked when you set both the html and body tag to height 100%. I still set both html and body out of habit for viewport, but there's no need for that now. Just use viewport units with the added benefit of being semantic.
Also, consider using the semantic dialog tag. It'll fall back to a regular div on non-supported browsers. But if the intent is to have a fullscreen dialog show, then it'll help screen readers know what's up.

Wow, thanks for the tips. I really appreciate it.
I was just going for the absolute quickest way I could get a div to go fullscreen.
I will examine the JSFiddle more closely and make some changes.
Thanks again.

Just checked the fiddle again and there was a tiny bug in it with the hidden style. If the dialog tag is supported then most browsers apply an automatic user agent style to it. So, forgot to add padding and margin resets in the class.
This fixes it: Clickety. So should work if you apply the hidden class to either the popup or the main tag.
It's worth noting this isn't an modal or modeless overlay dialog anymore, but quite literately replaces the main content while still allowing for having a nav bar up top. If it were an overlay that just covered the whole thing (drop shadow etc.) then absolute positioning is the way to go. But, IMO overlays don't look nearly as modern as this does.

Not a Javascript programmer, but I guess the extra semicolon?
|

You got it!
It was the semicolon located after the second style.
That just blew my mind! I will make no more mistakes with semicolons (he said doubting himself). 
#first{
background: yellow;
}
#second{
background: cyan;
};
.fullScreen{
width: 100%;
height: 90%;
z-index: 20;
position: absolute;
top: 12%;
padding: 10pt;
}

I have similar code I used to swap between dark and light theme css file, selected via a checkbox:
function switchCssMode() {
var chkMode = gebi("chkSwitchTheme");
if (chkMode.checked) {
document.querySelector("link[href='css/lite.css']").href = "css/dark.css";
}
else {
document.querySelector("link[href='css/dark.css']").href = "css/lite.css";
}
}
function gebi(el) {
return document.getElementById(el);
}

For modern browsers, you could do that without any JavaScript. Set up the colours to use as CSS variables / properties[^] in the :root context; use those variables throughout the stylesheet; and use the :has selector[^] to switch between dark and light themes.
:root {
--background-color: white;
--text-color: black;
}
body:has(input[id='chkSwitchTheme']:checked) {
--background-color: black;
--text-color: white;
} Demo[^]

I'm going through a book right now which is fantastic!
It's the best intro to OSes (how they are designed/programmed) I believe you'll ever read.
First of all, you can read it for FREE online (PDFs).
Operating Systems: Three Easy Pieces[^]
Have you read the book? It's fantastic because it starts out with simple code examples (in C) that teach one specific point at a time. Amazing!
If you've never read it, please skip all the (intro nonsense) & go right for the meat (to get an idea of how great the book is). Read this chapter[^] (be aware this will open the PDF in your browser) & I believe you'll be convinced how great the book is too.
And Now For the Weird & Wonderful
While examining the common_threads.h file for the 3rd example I stumbled upon these lines:
#ifdef __linux__
#include <semaphore.h>
#endif
I always wonder about strange things like that and in this case I thought, "Where is the __linux__ defined?"
I looked it up and discovered Gnu docs for the C PreCompiler (cpp exe)[^].
I tried the command they suggested:
$ cpp -dM
But when I did I could see that cpp was running but just had an empty string.
You actually have to point it at an exe and it'll pull out all the preprocessor commands. What!?!
$ cpp -dM ./threadx
When I ran that I saw a huge list of PreProcess commands. Huge!
I then ran it thru grep like this:
$ cpp -dM ./iox | grep -i linux
I saw the following!!
#define __linux 1
#define __gnu_linux__ 1
#define linux 1
#define __linux__ 1
So, I can see that over the years the convention to determine which OS the compiler is running on has changed. 
Wow, things get messy as time goes on, don't they.
BONUS
Here's my favorite pre-processor define I found in the list. 
#define __FLT128_DENORM_MIN__ 6.47517511943802511092443895822764655e-4966F128

When I open the link, it tells me that the PDF version is USD 10. I am not that curious about the book.

I re-tried both links (the one to the book's main web site) and the one directly to the PDF & both worked for me.
Honestly the book is free so I hope you get a chance to take a look.
Someone else has confirmed that they links worked too.
Try the link to the main site and then try clicking the chapters in the grid. Maybe you'll be able to get it there.
