Styles to reset css for all browsers
Jan 31st
The goal of a reset stylesheet is to reduce browser inconsistencies in things like default line heights, margins and font sizes of headings, and so on.
The reset styles given here are intentionally very generic. There isn’t any default color or background set for the body element, for example. I don’t particularly recommend that you just use this in its unaltered state in your own projects. It should be tweaked, edited, extended, and otherwise tuned to match your specific reset baseline. Fill in your preferred colors for the page, links, and so on.
In other words, this is a starting point, More >
Center align with float left or right
Jan 31st
Some said that you cannot centre floated elements but this is not quite true. It’s true that usually you can only float left or float right but if you have a group of buttons (for example it is menu) and you want them to be fluid in width then it would be nice to have them all float in the centre of the page. There is no problem if the floats have a width because you can then ascertain the main parents width and use margin:auto to center the whole block. However that means that the floats cannot be a More >

Scroll to anchor with jQuery
Jun 5th
Today I needed to create link with anchor. When I pushed it, it opens new page and add class to div. The source code is:
var class= window.location.href.slice(window.location.href.indexOf('#') + 1).split('#');
if(class){
jQuery('.testimonial_cont').find('.'+class).show('slow');
jQuery('html,body').animate({scrollTop: jQuery('.testimonial_cont').find('.'+class).parent().offset().top},'slow');
}
Of course you can change slow to normal or fast or even a int in milliseconds.
I hope it will help for someone.
