JavaScript Dynamic Elements:

Dynamic elements are just regular HTML elements that are actually created by the browser and only exist during runtime as part of the DOM. There are a handful of ways a dynamic element gets created. Rather the creating a <div> like so in a HTML page, we would create a <div> using JavaScript as so:

const divName = document.createElement("div");
divName.setAttribute("class", "div-style");
divName.setAttribute("id", "div-function");

Here we create the element, and also assign attributes to the element in a similar way. The CSS attributes will still be picked up by style.css if linked and the new given style will be applied. Similarly the id would be called upon by a function if there is a function required for the element.

Wireframes

The wireframe below, shows the skeletal plan of the app. The general concept was for the background and styling to stay the same, but the inner HTML content of teh center <div>to change upon user/function interaction.

Features

there is a timer that counts down from 40, giving teh user 10seconds per question
for every wrong answer 5 seconds are deducted by the timer
correct and incorrect answers both prompt an alert
