Which technology to use?

#1

Hi. I am trying to make a webpage which contains a search button. This button has a link so when I press the button, it redirects me to that link.
What I want is that on clicking the button, the content of the linked page is displayed just below my search button keeping the content of previous page intact. Just the information from the linked page is added below.

Currently I am familiar with HTML and CSS. What technology should be used for this purpose? Any pre-requisites for it? Any resources are welcome

adding content to a webpage dynamic is done using Javascript (or any javascript library to simplify this process)

its possible to scrape data with JS as well:

not sure its the ideal solution, but its possible. Search request are more often made to the back-end of a website.
