Menu
I'm currently working on html rich text editor for my iOS application,so,the setup is simple,i have a UIWebView loading my editor code,the html input is a 'contentEditable' DIV.
The problem is that every time i select this div to enter some text,a light gray frame appears on the input frame,telling the user that the textfield has been selected.
NOTE:You can see the effect in this quick video
My question is:How to remove this light gray frame?
My html file is bellow:
<html>
<head>
<style type="text/css">
:focus{
outline:0px solid transparent;
}
DIV::-moz-focus-inner {
background-color:#ff0000;
border: 0;
padding: 0;
}
ul{
margin-left:-10px;
}
ol{
margin-left:-10px;
}
blockquote {
border-left:#ff0000 5px double;
margin-left:0px;
}
</style>
</head>
<body onload="addImgAttributes();checkBlockquote();" topmargin="0" bottommargin="0" leftmargin="0" rightmargin="0">
<div
id="content"
class="content"
contenteditable="true"
style="font-family: Helvetica; background-color:#fff; color:#000; height:258px;"
autocapitalize="off"
autocorrect="off"
autocomplete="off"
spellCheck="false"
>
</div>
</body>
</html>

After the comment of @StephenJ i realized that this gray frame might be a subview of the UIWebView and not a css property.I logged the view hierarchy from the UIWebView in the exact moment that the frame appeared,this is the log:

After analyzing all these subviews i found one named UIHighlightView,as the name confirm,this view might highlighting the webView.So my second question is:How to remove this view?

It's as simple as setting the following CSS rule.
div {
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}
This makes the applied shadow transparent so it seems like it's gone.
Edit: Here's a demo link.
