I am working on a software project that will allow the user to create a chat. My application will have a chat button which when clicked by the user will trigger the display of a rising half page spanning the screen in length and which can be topped, like this:, Here I take a example on the vscode console and the circled button is the button I would like to create at the top of the window to allow overriding it. My main concern is that I don’t know how to create this type of page and when I search the web I see tutorials for creating modal windows and courses for getting started in reactjs. I’m brand new to reactjs and hope to get help from more experienced members of the community.
Thank you for reading my question and I look forward to your responses.
