How to remove Weird VS Code Suggestions as HTML Tags?

Whenever I code, in almost all types of file extensions i.e js, jsx,html,ts. I get these weird inline suggestions to make it as HTML tag. I truly tried everything out, checked out extensions, JSON settings, unchecked all the suggestions/autocomplete settings. But, this never goes. I don't know what to do, I am truly fed up of this.
And it always suggest whenever I put : in front of anything. Like below.
Wierd Html tags suggestion
It's so annoying. VSCode experts please help.
I have been trying to remove this from long time, I also checked the vscode IntelliSense documentation, and did all the troubleshooting but it still didn't help.

Strange HTML and CSS behavior

One of my clients has been encountering this issue when she goes onto the app. I was wondering if anyone had any idea how to get it to show normally? Im not sure if this is a code issue or her computer.
Everything is getting bunched together
Edit: I did not provide the code because it is very lengthy and I feel like there could be another answer that isn't linked to my code since it is only happening to that computer.
There really isn't a lot to go off of this. It could be as simple as changing the width of the input tag which would take almost no time to fix. If you're using bootstrap or some other framework maybe a class name is messed up somewhere in the html. It would be a lot easier to pinpoint what exactly the problem is if there were code to go along with it. Also there could be no problem with the code and could just simply be her machine, but there is still no way to figure that out without looking over it.

Website FB-Comments not showing up right

I didnt find an answer for me. so maybe you can help me.
I embedded the facebook commentbox in my website and finally the box shows up. but it seems that the is not high enough to show up well
I tried to put a height-tag into the code, but the problem remains.
Has anybody an idea? The Code is the one I got from the developers page
<div class="fb-comments" data-href="my website url" data-numposts="5"></div>
Thats what happens
I got it!
I had to allow the facebook-cookies in my browser.
I'll leave the question, maybe it could be useful for someone else.

Can't make line-spacing in DIV like as in TEXTAREA?

I've found that we can use DIV as a TEXTAREA by setting contenteditable='true' and overflow='auto' (or 'scroll') (I don't care about the appearance, just the functionality), but I really can't find the solution with Google search to make it really like a TEXTAREA, the problem is related to line-spacing, when pressing enter key, the next line is too distant from the one before in DIV. When designing with DreamWeaver, if I try editing the DIV's content and pressing enter key and switch to the code window, I can see there are P tags automatically inserted. That's why the lines in DIV are too distant from each other and it can't look fine like in a TEXTAREA. I want to say that it is so ugly and awkward.
Could you please let me know how to suppress that nasty automatic insertion of P tag into DIV's content whenever pressing Enter key? Or could you give me any other solution to make the lines in DIV normal as in TEXTAREA?
Thank you very much!
Your help would be highly appreciated! (I'm just a newbie in Web programming, so please be patient!!! Thankssss!! :))
UPDATE!!!
You may all misunderstood me, when I say I press the Enter key, it is not in code editor like DreamWeaver, It is when I load the page in the browser and try typing as a normal user. That's when I test the page.
Something like this?
#myDiv p{
margin: 0px;
}
I'm not 100% sure that the margin is what is causing the line height issues, you may want to try changing height, padding, etc. until you figure it out.
I tried making a fiddle and I'm not having the same problem, line spacing looks normal to me: http://jsfiddle.net/dFzjT/
Upon closer inspection, Chrome is adding extra divs upon each newline.
Switch to edit in the code view instead of the WYSIWYG HTML editor. Then you will want to type in between the opening and closing div tags:
<div>your text here.</div>
I've found that the strange problem (which might make some of you think I'm noob?, vote down me?) was not the fault of mine, it was the fault of the browser I was using, it was Opera browser. I didn't think it renders the DIV's content that way.
After try using a different browser like Google Chrome, FireFox and it is normal now, like a TEXTAREA as I want.
Thanks!
Here's the thing.
A lot of the answers on here answer the question, but they all miss an important point.
We were all new to this at some point.
So let me give you some advice that I wish I got when I started down this road.
Learn to read the code, and your life will be easier.
It might seem daunting now, but trust in your own ability to learn, and just struggle for a few days. You'll come out on the other end with a headache and a smile.
Write the code, save, and refresh the page in your browser.
This way, you look at it in a browser.
You should also get yourself all the important browsers: Chrome, Firefox, Internet Explorer, Opera & Safari.
Learn to use a localhost server like MAMP / XAMPP / Visual Studio.
This way you can write server-side code; that way you can test, check and tweak - all without having to upload anything.
Most of all, though..
Stay away from the WYSIWYG.
They're all just bad news.
Just write your own code.

Random css class from nowhere

I have a problem on a page i'm coding. Problem is i'm getting random img classes from nowhere (at least nowhere i know). I've put the generated class below.
<img class=" iryjanjabqqmypymdnuv" src="some/source/path">
There are several jquery plugins and jqueryui on the page but div that got img has nothing to do with those js libs. I also use php but that must have nothing to do with this i guess.
If you need any codes or names of the libraries just ask. Please help me i really have no idea and all the search i did was empty about this.
I had exactly the same problem. Find out that AdBlock Plus is responsible for that. So, just disable all the extensions and reload the page
Just wanted to chime in for anyone that finds this googling their problem, this is exactly the right answer in my case as well. AdBlock Plus (in Firefox only, not Chrome) was generating random class names for images I have embedded in my nav bar for social media links.
Now I have to either find a way to get around that or anyone using ABP in Firefox will see a weird looking nav bar due to this issue. It's not exactly an unpopular plugin.
I work in both Chrome and Firefox and use ABP in both. Hopefully we won't have to find workarounds for this.
Is it possible that you're browsing on a mobile network connection? Some mobile networks modify the HTML/CSS for images so they can serve lower-bandwidth versions, but allow you to "fix" them later. For example, on T-Mobile, if I hover over an image it will give me an Alt tag telling me the keyboard shortcut to use to load the original.
Obviously this won't be the case if it's all local...
I had the same problem and disabled all extensions in Firefox and then it was gone. Not sure which extension is the guilty party, have too many to chase it down by disabling each of them one at a time. :)
