Bug on blog posts

Hello!

I use the following code to increase the width of blog but now I have a bug, the text is centered. Do you have a solution? please

/* Width Blog Posts */
#top .fullsize .template-blog .post .entry-content-wrapper > * {
max-width: 770px;
margin-left: auto;
margin-right: auto;
text-align: center;
}
#top .fullsize .template-blog .post .entry-content-wrapper {
max-width: 770px;
}
#top .fullsize .template-blog .post-title {
max-width: 100%;
}
#top .side-container-comment-inner > * {
max-width: 770px;
margin-left: auto;
margin-right: auto;
text-align: center;
}
@media only screen and (min-width: 768px) {
div.comment-entry.post-entry {
    width: 72%;
    margin: 0 auto;
}
