I am currently working on positioning text and a button over an HTML5 video without using media queries to address mobile display issues. The problem arises when using the car-image-overlay class from Bootstrap 4 to show the div containing the text over the video. Despite trying various Bootstrap 4 classes for alignment, such as centering and left aligning, the layout breaks on mobile devices like the iPhone 5e. The button, h1, and p elements do not adjust, causing them to cover the entire video and go out of frame. I initially expected Bootstrap to handle this seamlessly, but it appears I may be implementing it incorrectly. I have tried utilizing col-lg and xs classes, but to no avail.
