Problem wrap text around an image

Hello everyone !
Like it’s written in the titel, I can’t wrap a text around an image. I googled the problem before exposing it here. I aligned my picture left. in the visual everything is right but on my website it doesn’t work and look like that : http://www.skandersaadi.com/?page_id=126

I added this code totally at the end of my style.css like someone advised in another post but it’s still not working :

img.centered, .aligncenter, div.aligncenter {
	display: block;
	margin-left: auto;
	margin-right: auto;
	}

img.alignright {
	padding: 4px;
	margin: 0 0 2px 7px;
	display: inline;
	}

img.alignleft {
	padding: 4px;
	margin: 0 7px 2px 0;
	display: inline;
	}

.alignright {
	float: right;
	}

.alignleft {
	float: left;
	}

Here is what is written in my text editor :

<a href="http://www.skandersaadi.com/wp-content/uploads/2014/04/skander3.jpg"><img class="alignleft size-thumbnail wp-image-9" src="http://www.skandersaadi.com/wp-content/uploads/2014/04/skander3-145x145.jpg" alt="skander" width="145" height="145" /></a>As it so contrasted oh estimating instrument.
