Hello, I am creating my portfolio, and I am learning how to use a parallax effect. I am having an issue where my first parallax image does not seem to properly render the height css attribute if it’s a percent or “auto”, but it will render if the attribute is set to a certain amount of pixels. Can someone please help me through this? I would rather not set it as a hard pixel value because it may not show up properly on some screen sizes.
My portfolio link is: http://codepen.io/oaak001/pen/qRQPQP
The css element in question is: parallax_image_01, located on line 16 in the HTML segment, and line 11 in the CSS element.
Any help or advice would be welcome. Thanks.
