HTML anchor element has an 'invisible' button-CodePudding

I created both clickable icons and button that will redirect to external links but I've just noticed these 'invisible' buttons exist. I also know that these clickable spaces are the original positions these icons/image are from and I have used "left: xx%" to reposition them but how can I make this 'invisible' buttons disappear or is there any better way to reposition these icons/button?

The icons are not visible as I'm using an external stylesheet and I can't seem to include it but the button is and pressing the tab button on the result screen will show the problem.

CodePudding user response：

First of all It is illegal in HTML5 to nest Button tag inside a tag.

The reason this issue is happening is you are giving left and transform css to button but a tag is still at it's original place.
