Text left and image right

Question

I'm trying to make text left and image right in the div. I found many examples in Stackoverflow where image is left and text right, then i tried to switch them but can't make it work. I found that on stackoverflow but doesn't make sense for me.

I've tried this JSFIDDLE but you'll see that it wont works.

.main-topic {
    border: 2px solid green;
    width: 1541px;
    margin: 0 auto;
    clear: both;
}

.left-text{
    vertical-align:middle;
}

.right-picture{
    float: right;
}

.right-picture > img{
    display: block;
}

.clear{
    clear: both;
}

My goal is this (sorry can't post image i haven't enough reputation). I want that text be left side on the bordered div and picture in the right side

Answer 1

Just add display: flex; to .main-topic will do the trick.

And remove following css. There is no need of it now.

.right-picture{
    float: right;
}

Working Fiddle

Edit:

If don't required static width and height then, remove static height from section and static width from .main-topic will make result better.

Which is width: 1541px; from .main-topic And height: 500px; from section

Updated Fiddle

Answer 2

Remove float:right from img and put float: left in .left-text

"We've all seen the trailers, the magazine covers, the viral videos, and the billboards by now, so what's left for Deadpool (Ryan Reynolds) to do?" creator Andrew Stege asks in the petition, which is directed to SNL, creator Lorne Michaels, parent.
