How to send HTML content from one page to another

I am building a sort of job listing platform. When companies complete the input form specifying their needs, how can I use that input content in another page to display it on the job board?
A sort of document.querySelector(‘class’).innerHTML to select it from the other page, and display it.

Thanks in advance. I am learning JS to go through with some projects I have in mind.

I’ve seen people say I need PHP or something called JQuery. Is it possible to do it without? Or could someone point me to a course I could follow teaching specifically that?
