1. Create the css property either Id or class in the following rules ( In this Example i will Use id )
#ads160 {
width:160px; ( width of your adsense unit)
margin:0 auto;
}
Then place your adsense code in the div created for them:
<div id='ads160'>your 160px ads unit here</div>
in some cases if you are trying to place the same ads unit sizes for multiple div it`s always better if you code them in classes just like the following rules:
.ads160 {
width:160px; ( width of your adsense unit)
margin:0 auto;
}
<div class='ads160'>your 160px ads unit here</div>
In this way you can place up to three ads unit centered with only one Css Class.
Note : The above codes is primarily to instruct the element to be centered inside any div but if your want to make the ads showing in a Div That Stay At The Bottom / Top of Page, you can try Creating Static Footer / header With CSS
