Hover is not working on IE11 and Edge when the mouse pointer is on the iframe RRS feed

  • Question

  • Hello there,

    I am trying to make iframe expanded and shrank when the mouse pointer is on the iframe by using media query.

    However, it is not working, but, when the mouse point is on the frame border then it is expanded and shrank.

    Here is my source code.

    <style type="text/css">
    	width: 80px;
    	right: 0;
    	width: auto;
    	-webkit-transition: width ease-in-out 0.1s;
    	-moz-transition: width ease-in-out 0.1s;
    	-ms-transition: width ease-in-out 0.1s;
    	-o-transition: width ease-in-out 0.1s;
    	transition: width ease-in-out 0.1s;
    @media all and (max-width: 2500px) {
        width: 50%;
    @media all and (max-width: 900px) {
        width: 55%;
    @media all and (max-width: 800px) {
        width: 60%;
    @media all and (max-width: 750px) {
        width: 65%;
    @media all and (max-width: 700px) {
        width: 70%;
    @media all and (max-width: 650px) {
        width: 75%;
    @media all and (max-width: 600px) {
        width: 80%;
    <iframe id="sidebanner" src="" frameborder="1" marginwidth="0" marginheight="0" scrolling="no" allowtransparency="true" style="top: 0px; height: 100%; right: 0px;"></iframe>

    Also, this source code is working on chrome, FireFox and Opera.

    Only IE and Edge is not working.

  • Hi SosekiM,

    First, -ms-transition is not a valid CSS property, you need use transition directly. 

    About why transition doesn't work in IE, please check this link:

  • Dear Eric,

    Thank you very much for your help.

    I tired adding <!DOCTYPE html> and <meta http-equiv="X-UA-Compatible" content="IE=edge" />.

    However, it dose not work at all.

    The issue is that when the mouse pointer is on the iframe, it dose not change the width defined in the media query.

    Do you know how this can be fixed?

  • Hi SosekiM,

    Please try add this line code to your page:

     <meta http-equiv="X-UA-Compatible" content="IE=9;IE=10;IE=Edge,chrome=1"/>

  • Dear Eric,

    Thank you very much for your comment.

    I tried that one too and still did not work at all.

    What I expect is that when the mouse pointer is on the iframe, its width change from 80px to what I defined in the media query.

    It dose change the width when the mouse pointer is on the iframe border, but, when the mouse pointer is inside iframe it goes back to 80px.

    So, it seems to me that IE and Edge do not detect mouse pointer when the mouse point is inside iframe.

    If this is IE specification then I just give up because there is nothing we can do right now.

    I give you an example of what we want to get.

    Best regards,

  • I can't believe this still hasn't been resolved, or that no one seems to have an answer. We are having a similar issue with the close video 'x' button when a video is playing in the iframe hero area. It only happens on Microsoft edge and internet explorer. When you are on the bottom of the iframe, the close button appears as it should. When you hover the cursor over the playing video, the close button disappears and the user can't click it it to make the video go away. This is frustrating Microsoft...

    Well javascript/JQuery it is, I guess...
