When you focus A tag or submit button sometimes outline border looks ugly on websites. Here are examples:
Foobar

This can be easy fixed (for all browsers except Internet Explorer!) by adding 1 line of CSS rule:
a:focus { outline: none; }

IE has non-standard HTML attribute hideFocus=”true” to solve this problem. Of course you don’t like to put this attribute in every <A> tag and submit buttons in your HTML. I have 2 working solutions for all browsers:

CSS expression solution

input, a {
  outline:expression(hideFocus='true');
  outline:none;
}

jQuery solution

$("a, input").each(function() {
  $(this).attr("hideFocus", "true").css("outline", "none");
});

‘Notify Bar’ plugin

Simple plugin (basically it’s not a plugin, but widget) to show notify bar
(like on Twitter’s webpage).
It’s very simple to use:

      
$(function () {
  $.notifyBar({
    html: "Thank you, your settings were updated!",
    delay: 2000,
    animationSpeed: "normal"
  });
});
      
    

and to your html page stylesheet:

<link rel="stylesheet" href="jquery.notifyBar.css" type="text/css" media="screen"  />

$.notifyBar can pass next parameters:

I really like when gallery or application with pagination uses navigation with arrow keys. Like here.

Nice and fast navigation I think. So you can read the main article about this navigation on Lebedev’s site (or in Russian). This features is at least 3 years old and is used so rarely, but it’s so useful and makes users happy.

So I have written a tiny plugin for jQuery (based on the Andrey’s code) for this navigation. You can see my demo and price how useful it is.

Here is the stuff and how to use it
