pass parameters by id in url

When you are passing parameters in the url, remember to pass the parameters by their id, not value. It would be better.

For ex, if you have to pass the "city" parameter to a file called index.php, do pass it as: index.php?city=2, not like index.php?city=bangalore

It would be readable and also easy to use the values in our queries, with out much validations. (probably only integer validation is needed!)
Especially when we are using ajax calls, this is useful.

css link remove dotted outline

Its quite awkward to look at the link, when it is clicked and the dotted outline appears on it. To overcome it, just add the following line to your css file: a { outline: 0; } For example, to remove the dotted outline for the menu links on your page, add this to your css: #navigation li a {    outline: 0; } ( Assuming you have this menu structure: <ul id="navigation"><li><a href="news.html">News</a></li></ul> )
