Hi all,
Wondering how to make a slide gallery in html on an existing page. I have multiple existing imgs in my code already and I want to assign a style to all of the slide gallery imgs without assigning it to other imgs. I also want the gallery to appear max-height and max-width as currently am displaying it in an iframe which is tricky. Full code for additional gallery below

Below a fixed example for a 3D sphere
Challenge:
Design and implement an algorithm that takes as input a smooth, parametrically defined 3D surface described by analytic formulas. This algorithm should automatically determine a suitable projection center for stereographic projection and compute the corresponding 2D projection. The algorithm should then reconstruct the original 3D surface from this 2D projection. The quality of the projection (projection center selection) and the...

I have a div that displays user-edited content ready to be sent to the Windows Print Dialog for printing. The content contains images and text at a width of 7016px, which is the width of A1 at 300dpi. I have a button to print at A1 and a button to print at A4. The A4 button changes the width to 2480px to fit onto A4 paper. But when the dialog opens, the image is huge and takes up about 7 pages of A4 paper. In order for the image to fit I need to manually change the scale to 10.
How can I...

The screen looks like the above and the background bogs up and down. A lightning flash can happen and tests successfully.
However, the SetTimeout() timer that has lightning flash every now and then is not working.
Here is where the animate() function happens and where the timeout is called and it doesn't work.
Here is where the lightning effect is coded and it works successfully if there is no timeout ..read more

I have a CSS animation with an absolutely positioned wrapper div and 2 sibling child divs with text, but the wrapper collapses in Safari and doesn’t honor the child elements inside of it. Is there a workaround? Here is the page with the issue in the header image. Innovation Grove | Rose-Hulman ..read more

When I delete hit_top variable in script.js and roomEffects.js that is sent into the function, then the background scrolls upwards as it should. But without the hit_top variable, how can I tell the program that the background has already been to the top of the screen? It should look like a bogging ship.
In script.js
Code:
import { bog_ship } from './roomEffects.js';
const canvas = document.getElementById('canvas1');
const ctx = canvas.getContext('2d');
const CANVAS_WIDTH = canvas.width = 640...
