Welcome back.
In this video, you will learn what is XHTML, you might have heard about SDM a lot of times SDMI means
hypertext markup language.
HDMI is a kind of language.
So I'm talking to you in English.
I know English, you know English.
That's why we can talk to each other.
Similarly, when your browser talks to you do observe a YouTube sense the data in a language called
SDMI, YouTube server and all that language, your browser knows that language so your browser can make
sense of that data.
If somebody doesn't understand the language, he will think that language is just a bunch of noises.
So this is how this Gmail looks.
You can go to YouTube dot com in Google Chrome and then you can right click after clicking like you
can view source, you will see the e-mail.
That thing will make no sense to you, but it makes all the sense to your browser, your browser processes
that HTML and then it displays the video in a form which you can understand.
It shows you the play button, the pause button, the volume button, all those things which you can
understand.
My browser makes sense of that and shows you that data.
This is called HDMI.
OK, so now if you I feed you some funny things you can do by changing HDMI.
OK, so this is Facebook of Irun and we are going to make Amitabha to like one of his picks.
OK, so let's say we are talking about this picture and at the bottom it says we're kissing and nine
others like this.
And there is one comment on this picture.
OK, we are going to make this.
We are going to increase all the likes and comments and we are also going to make Amitabha just like
this.
So we are going to press inspect element.
Then we are going to select that piece of HDMI.
Look, after that, we will go in that menu and we are going to edit that Yamal will press editors e-mail
and then we you can see the text we kissing and nine of those, OK, we are going to edit that, we
are going to delete that and we are going to type
AMITAVA and one thousand something people, one thousand of those like this.
So that we then after we do that, it will show the same on the Facebook.
Weatherbeaten and.
Let's say one thousand thirty five others.
I'll just play God bless and get anywhere else.
And now when I
open the Facebook again, it will it says Amitabha and one 1035 others have like this.
I can edit as many things on this page in that region because ultimately this entire thing is XHTML
Facebook friends, e-mail your browser displays XHTML, I can edit the HTML and my browser will display
that only so I can show it to my friends.
I can screenshot it, I can make a video recording of it and it will stay like this.
But if I reload this page it will go away because when I reload, Facebook will send it again and that
e-mail will contain only the real thing.
But once HDMI reaches me, I can edit, edit it and show it to my friends.
See you in the next video.
Thank you.
