A links
<a> by default have a dotted outline around them when user click it, and it will be a gray color around on it.This is default styling for the purpose of accessibility. For folks without the ability to use a mouse, they still need some visual indicator that they currently have a link active.
To remove the dotted outline, just include this as a part of your CSS
a:link, a:hover, a:active, a:focus {
outline: 0;
}

This was my first time facing this problem. When I post more than 1000 variable value to server, it only show me 1000 variable received and the rest was missing.
To solve this problem you need to increase
max_input_vars number in
PHP.ini to 3000 or 5000. It was because the
max_input_vars default value was 1000. If you post more than the value server will ignore the rest.
if your server uses the Suhosin patch or after change the
max_input_vars number the problem still same. you can try add
suhosin.post.max_vars = 3000
suhosin.request.max_vars = 3000
to increase the maximum number of post variable.
