What could be causing the background color opacity of the HTML hr tag to decrease?

I am trying to modify the height and background color of the <hr> HTML tag. However, even though the height and color are changing, it appears that the background color opacity is decreasing slightly. What could be causing this issue?

Here is my code:

<hr class="mb-4" style="width: 10%; margin: auto; height: 10px; border: none; color:#f24516; background-color:#f24516;">

How can I maintain the original color and what might be causing this problem? I am using the latest version of Chrome on Windows 10.

When running the entire code in the browser, I see the following output: https://i.sstatic.net/yq0Cz.jpg

Here's the complete code snippet:

Answer №1

Your bootstrap folder contains a reboot.css file with the property opacity: .25. To override this, simply add opacity: 1 to your hr element.

Answer №2

In your reboot.scss file, there is a style for hr with opacity:.25;. To correct this, add the following code:

        hr {
          opacity: 1;
        }

Here is the updated HTML code snippet:

<hr class="mb-4" style="width: 10%; margin: auto; height: 10px; border: none; color:#f24516; background-color:#ff0000;">

Additionally, ensure that the CSS properties are correctly applied in your HTML document. Here is a sample starting HTML template:
