ie8 transparent background cannot be clicked_html/css_WEB-ITnose

Recently developing a website, the requirement is three on one screen. Only half of 1 and 3 can be seen, 2 is displayed in the middle, and there is no arrow button.

Because I have written a plug-in with front and back buttons before, and I was thinking about how to modify it, so I removed the background of the front and back buttons and positioned them at positions 1 and 3 to achieve front and back clicks,

I found that the button would not work no matter how I changed its level under IE8, so Baidu later learned that this was a bug of IE. Elements with transparent backgrounds would cause the click event to fail. Very sorry.

So I have to go back to modify the script or add a transparent background png.
