CSS CSS Layout Techniques Display Modes Block vs. Inline Elements

"now we have a little more control over our layout"

Hi, my question is not unique. There is the same question here: https://teamtreehouse.com/forum/body-vs-wrapper-div-a-little-more-control

But there is no answer!

Could, please, Guil answer it in detail and with examples?

The reason he says it adds more control is because of css's specificity trait. By adding a class to the html tag with the value "wrapper" you can now directly control that class within the css, for example:

.wrapper {
    margin: 0 auto;
    width: 1000px;
}

body {
    margin: 0;
    width: 900px;
}

In this example, .wrapper takes precedence over body due to specificity. If you had multiple body elements, only the one with .wrapper would be styled with the .wrapper styling, hence giving you more control over your css styling. Hope this helps!

Thanks it's clear now
