Custom theme article and aside

Hi all,

I have a custom theme that i developed in html5 & css3.
The post area is in a section>article part and the sidebar in a section>aside.

When I use the get_post and the_excerpt method in the post article area only the first post title shows up and excepts of the next posts. The sidebar then is in the post area.

I have tried to float the article area to the left and the aside to the right, with no success :/

Here is the css code of those two areas:
NOTE: The #main is the section with that ID

#main {
		display: block;
		width: 96%;
		max-width: 980px;
		margin: 1.25em auto;
		padding: 0em;
	}

	#main article {
		display: inline-block;
		width: 65.3%;
		background: #fff;
		vertical-align: top;
		margin: 0em;
		padding: 0em;
		text-align: center;
	}

	#main article a {
		font-family: Tahoma, sans-serif;
		font-weight: 100;
		font-size: 0.8em;
		color: #f46523;
	}

	#main article img {
		max-width: 560px;
	}

	#main article h2 {
		padding: 1em 1.8em 1em 1.8em;
	}

	.post-meta {
		display: block;
		text-align: left;
		line-height: 1.25em;
		font-family: Tahoma, sans-serif;
		font-weight: 100;
		margin: 0em;
		padding: 1.25em;
		text-align: justify;
		font-size: 0.8em;
		color: #777;
	}

	.post-meta a {
		color: #f46523;
	}

	/*sidebar*/
	#main aside {
		display: inline-block;
		width: 30.6%;
		margin-left: 3%;
		padding: 0em;
		vertical-align: top;
	}

	#main aside section {
		margin-bottom: 1.563em;
		background: #fff;
	}

	#main aside section ul {
		padding: 0em 1.875em 1.25em 2.5em;
	}

Thanks in advance
