Use any of these CSS styles.
a:active, a:focus,input, input:active, input:focus{ outline: 0; outline-style:none; outline-width:0; }
a:active, a:focus,button::-moz-focus-inner, input[type="reset"]::-moz-focus-inner, input[type="button"]::-moz-focus-inner, input[type="submit"]::-moz-focus-inner, input[type="file"] > input[type="button"]::-moz-focus-inner
{ border: none; }
OR
:focus {outline:none;} ::-moz-focus-inner {border:0;}
Once part of the CSS style is complete, you may also need to install an IE emulator. Update the web.config file for web applications and include the key under it.
