Lastpass bar with an iframe breaks my css - css

Question

I have two buttons are set position equal to "absolute", when the LastPass addon's bar dipslays, they displays wrong because LastPass had inserted an iframe to my webpage:
LastPass iFrame
<iframe id="lpiframe74158812" src="chrome-extension://hdokiejnpimakedhajhdlcegeplioahd/overlay.html?&add=1" scrolling="no"
style="height: 27px; width: 1263px; border: 0px;"></iframe>
The CSS:
.button-bar {
width: 175px;
float: left;
top: 113px;
text-align: right;
right: 20px;
position: absolute;
}

How can I avoid this case? Thanks so much!

Answer 1

I had this same issue and I found that last pass editing the DOM of my webpage! LastPass had added a div right after the body tag of my page.
<div id="lptopspacer48468746" style="height: 27px;"></div>
It looks like the div id is random, so I can't strip it out. I think this problem is with lastPass. I don't think there is a way to truly fix it.

Also annoyed by this <div id="lptopspacer[0-9]+" style="height:40px"></div> inserted in any page monitored by firefox lastPass plugin (after the site has shown a login form), I've come up with a jQuery solution.
Only adding some CSS rules don't seems to works as the div is obviously added after page load by a script. Changing style or trying to remove the div just after page load doesn't works either.
So this snippet run a delayed function to hide the div when found, or stop running after 5 attempts if no lastPass plugin is affecting the document.
<script>
var log = function(msg) {
if (console && console.log){
console.log(msg)
}
};
$(document).ready(function(){
var maxTry = 5, lptopHideTimeout;
var clearLptop = function(delay) {
var $lptop = $("div[id^='lptopspacer']");
if (lptopHideTimeout) {
window.clearTimeout(lptopHideTimeout);
}
if ($lptop.length && $lptop.is(':visible')) {
log("** Hiding lastPass lptopspacer...");
$lptop.css( "display","none" );
}
else {
maxTry -= 1;
if (maxTry > 0) {
log("## No lastPass lptopspacer div found yet. Retrying in " + (delay/1000) + ' second...');
lptopHideTimeout = window.setTimeout(function(){
clearLptop(delay);
},delay);
}
else {
log("## Giving up after too much attempts.");
}
}
};
clearLptop(500);
});
</script>

Better late than never if others also are having this problem. I had it to, that Lp spacer, in my case it was generated because I had Mcafee safekey installed on the computer. It showed up with a notice on every pageload on my website and caused an lp spacer that broke my site with a white bar on top.
Uninstalling Mcafee safekey solved it for me.
