</html>Upon clicking the button, a sudden dark blue outline appears around it. Despite searching through forums and Bootstrap documentation, I have not found a solution to change or remove the color of this outline.
I have attempted to modify the outline and box shadow properties with no success.
Please note that I understand the importance of visual cues and would prefer to simply change the color of the outline. However, if there is no alternative, I am open to removing it internally and adding a custom style in CSS.
EDIT: Just to clarify, the issue pertains to the 'subscribe' button, not the arrow button. I will include the code with the proposed changes and eliminate the border for better visibility.
