Causes and solutions for when the radio button check box on some sites disappears in the browser

Cause

The reason why the radio button check box is not visible on some sites is because the radio button has a style specified.

For example, Yahoo! AnswersIf you check the "Thank you for the best answer" radio button in the question above using the developer tools, you will see that a class is specified for the Input element.

If you remove the class specified for the Input element in the developer tools, a checked radio button will appear.

If you remove the class, a check mark will appear on the radio button.

If you further delete the large circle that hides the check, it will look like this.

There are two ways to deal with this:

1. Request from the website

To truly resolve the issue, you need to contact the website.

I'm not sure if they will be able to help you, but you could try asking the website you use to delete or change the style specification.

2. Temporarily enable the selection in your browser settings

For Google Chrome

1. Open Google Chrome and click "︙" in the top right corner > Click "Settings".

2. Click "Accessibility" in the menu on the left.

3. Turn on "Highlight items in focus."

Accessibility - "Highlight items in focus" — Accessibility – "Highlight items in focus"

This will cause a border to appear around the radio button when it is selected.

However, this frame will disappear immediately (in about 2 seconds), so it is only a temporary function to confirm whether you have made a selection.

For Microsoft Edge

1. Open Microsoft Edge and click "..." in the upper right corner > Click "Settings".

2.Click "Accessibility" in the menu on the left.

3. At the top, turn on "Show a high-visibility outline around the focus area of the page."

Display a highly visible outline around the focus area of the page

This will cause a border to appear around the radio button when it is selected.

However, this frame will disappear immediately (in about 2 seconds), so it is only a temporary function to confirm whether you have made a selection.
