Align text to the left

In your Child Theme or CSS Editor Plugin try this code:

.hentry.type-post .entry-content {
    float: left;
}

*Note
If your theme has a custom CSS Editor in it, you can also paste the code in there.

Never edit core CSS or PHP files under Appearance > Editor. Your edits will be deleted when the theme is updated.

thank you for the help. there is this horizontal line on top of my posts. The text is now aligned to the left but, i want the end of text to align at the end of the horizantal line, too.

Try this code:

.hentry .entry-header {
    margin-bottom: 1.631em;
}

You can lower the number to adjust more.

thank you. what i wanted to do is that the whole content of the posts align itself with the horizontal line. the content aligns only 3/4 of the horizontal line. An example is the Home page.

OK, try this code out:

.hentry.type-post .entry-content {
    width: 100%;
}

it worked, thank you for your patience and help @northwoods
