Make some CSS/JS changes in my website.

I have a website dashboard built using boostrap framework. I want a developer to do the following 3 things: a. I am using GrapeJS([login to view URL]) website builder in my website. I want to put in an additional form with a button. When the button is pressed, I want that the content of the GrapeJS editor is copied and pasted into the form and the form gets submitted. Perhaps GrapeJS already has a functionality for it, but you need to consult its documentation for it. b. I am using ChartJS library([login to view URL]) to display line charts. I want that in my line charts, I want to have a distance of 10 numbers on the x-axis. c. I have a form that allows users to select an image and submit the form. I want to improve the interface for that using modals for each image. The developer must be available to start work asap. Also due to my heavy CI/CD pipeline, I would need you download the site locally by using right click->Save As on the webpage, and then provide me the updated CSS file in the end.
