sorry, forget about this

.post.single .post-title {
display:none;
}

Because no one seems to know, I post here the ways I did it

.post-inner {
width: 100%;
}

.content {
width: 1200px;
max-width: 100%;
margin: 0px;
}

.content.thin {
width: 100%;
margin: 0px;
}

.post.single .post-title {
display:none;
}

body {
background: #ffffff;
}
