This is a sample grid with HTML (but not the CSS which I will copy below) and also the JavaScript file. These are typical of the sorts of files I use to create this website so here are some instructions for use.
Note that for a specific page, you would need the HTML file and you would also have to add the CSS and make sure that the HTML file links to that CSS file. The reason I don't add it as a separate file is because you only create that file once and then any HTML file that links to it and has the appropriate elements to form the grid. Once everything is in place, you can then create as many pages as you want simply be adding copies of the HTML page.
