Change background color and opacity of Home Page Featured Post details (Presidio)

Use this code snippet to change the background color and/or opacity of the box overlapping your Featured Post atop Presidio’s home page. This will only impact the background, not any of the post details, like the title, summary, etc. When using CSS to write opacity, use numbers, not percentages. For example, an opacity value of 1 equals 100% (meaning the box is not transparent at all). We recommend not making the box too opaque, otherwise it will be hard to read your post details. Try values like .9 (90%), .95 (95%), or as low as .8 (80%).

Here is a short video demo showing you how changing these two properties might look:
