    I only need a base of the website. For example: -- (1st domain name with .in extension) -- (2nd domain name with .it extension) I need two sites with differences in domain extension. First, we need to check what hostname we hit on the internet using "Next JS Middleware". After that, it will only return that site API. And that API JSON data we need to store in session. After that I only want one component to be rendered in the front end with the data stored in JSON format in session.

    Hello, We launched a guestbook plugin called Gwolle Guestbook, it is a nice plugin but we need to fix the formatting on how it displays to our users. Here is a live version of it: On mobile, you will see that the formating is way off (spaced out etc.), we need that fixed. As well, we would like to make the "Write a new message" button bigger with a black background and the font white. Also might be good to alternate the background colour for each message slightly, so: white, slight grey, white, slight grey etc.. For desktop, we'd like to also make the "Write a new message" button bigger with a black background and the font white. As well, have the colours alternate for messages to stand out easier.

    Improvements need to be made in a wordfind/wordsearch game in React. Quite simple game with randomly generated letters in a grid. There are three components in total: 1) WordGenerator - a function that generates random letters. Once the words are passed in it will generate a word grid with given words and random letters wrapped around them. It also takes orientation prop to generate letters in a given position, as well as width and height of the grid (integers). 2) WordSearch - a function that does handle the letter selection. On click and drag you'll be able to select the letters, once your mouse click is released it evaluates your selection to see if the word is found. If found then word is highlighted, else the selection is set to false and nothing happens. 3) index - is where ...
