Development of dynamic websites [closed]

I am new to web development and it is my very first project of dynamic website. I have to develop a website of programming tutorial, similar to w3schools. What I am confused about and wants to know is that do we simply make a template in the html or php file about how the tutorial will look like and all the content of all languages will be stored in database which will be dynamically fetched and displayed. Or we make multiple files for all the languages?

Which approach do we use for such website having multiple languages tutorials.

Reload page dynamically

I create a sahsboard to which I added a modal box which proposes to save or to go back. To go back, I need to reload the page (so that the data will return to the initial state). I used javascrpt and this script works but the problem is that the browser shows that the page is reloaded (I would like to reload the page dynamically). Do you have an idea to reload the page dynamically?

current code

function cancel() {
close();
document.location.reload();

HTML italics and non-italics text is rendered too close to each other

There is a rendering issue with text marked as italics when no extra space is added after the italicized text and before the next text span (non-italics):

Eureka!

<i>Eureka</i>!

which makes exclamation mark being rendered too close to the last italicized character a.

Engine: Google Chrome Version 90.0.4430.85 (Official Build) (64-bit)

Is there a way to solve this issue?

nmap puts service as "tcpwrapped" even though nignx is running on it

I have my own little website running with nginx on a digitalocean server.

I wanted to try to nmap it just for the practice, so I tried running

nmap -v -A -sV xx.xx.xxx.xxx

It scans and comes back with this response:

PORT    STATE  SERVICE    VERSION
22/tcp  open   tcpwrapped
|_ssh-hostkey: ERROR: Script execution failed (use -d to debug)
80/tcp  open   tcpwrapped
|_http-server-header: nginx/1.18.0 (Ubuntu)
| http-title: Welcome | MyWebApp
|_Requested resource was /public
443/tcp closed https

So the service on port 80 shows up as 'tcpwrapped' even though i know it's running nginx. the scan is however able the see in the serverheader that I am running nginx/1.18.0 (Ubuntu)-

What can be the reason that nmap can't tell which service I am running, when I am clearly running nginx?
