Can a self taught developer be accepted in these big companies without having to acquire a diploma or degree in college??????

Answer 1

Sure, in the end you're paid for your skills, not for having received education and being unable to utilize it. Even with a degree, you won't get far if you you don't deliver.

of course you'll need to convince someone to hire you. a degree is an argument for hiring someone. if they don't have one, they need other arguments.
the best thing to have to show for yourself, degree or not, is references. for an experienced programmer, those may be prior jobs and count much more than their education.

if you don't have any references, get some. learn to develop professional websites for friends, small businesses, maybe clubs/teams you're a part of...
not into web design? how about programming apps for mobile? games for mobile or maybe games in general? or maybe you got an interesting idea for a desktop application?

maybe your work will end up being a well-known open source project on GitHub (probably one of the best references possible). even if it doesn't, having programmed anything from start to finish is great.

Answer 2

HTML/CSS actually aren't programming languages. they only allow "describing" your content or what it should look like, but you can't implement any real logic. however, JavaScript does, although it makes more sense to deploy using a framework (jQuery/Bootstrap). to implement backend logic, PHP is most popular (although there's multiple alternatives).
note that, utilizing Bootstrap for example, you can easily and quickly create professional websites with just HTML/CSS and just a very minor understanding of JavaScript. PHP only comes into play when you have a big project requiring content and user management.

don't want to use PHP? Python has flask, django, brython and more. also there's Java Server Pages or Microsoft's Active Server Pages, among others.

Wow this journey is surely going to be tough 😖
Am a student I firstly started having this interest when I graduated from high school and gradually I started learning that was two years ago
Now that am in University my progress has been at a snail's pace still trying to cement HTML and CSS at full capacity
So before I go deeper are these fundamentals for all programming programs or I can start with any of my choice??????
