CSS Border radius, border color ghost corner borders in IE - css

Question

Morning,
I have the following code that works in all browsers other than IE. I want a blue border to appear when clicking on input boxes, however did not want to see the elements resizing and positioning. I fixed this by putting a border colour to match the background colour, thus removing the resizing effect. However, on IE, you get ghost borders which seem to be a combination of both the border radius and border colour (background colour). Any ideas of how to fix this without using box shadow?
Screen Shot showing ghost borders:
input,
textarea,
select {
position: relative;
display: block;
border: 3px solid #4f4f4f;
border-radius: 10px;
margin: 6px auto 22px auto;
width: 260px;
font-size: 13px;
text-align: center;
&:focus {
outline: none;
border: 3px solid #4cc7fa;
}
}
Many thanks!

Answer 1

You can do like this to overcome the ghost/resize/re-positioning effect, where you change border-width on focus and compensate its re-positioning with a negative top
body {
background: gray;
}
input,
textarea,
select {
position: relative;
display: block;
border: 0px solid gray;
border-radius: 10px;
margin: 6px auto 22px auto;
width: 260px;
font-size: 13px;
text-align: center;
}
input:focus {
top: -3px;
outline: none;
border: 3px solid #4cc7fa;
}
<input type="text">

I would use the following javascript:
Your-function() {
document.getElementsByTagName('input','textarea','select').classlist.toggle('show')
}
add display:none to input:focus
add the following css
.show
{
display:block;
}
Note: Add onclick="Yourfunction()" to your markup to load the js.
