I am having trouble closing an element and know WHERE the error is, but cannot correct it [on hold]

I am trying to edit a template for blogger and edited the code and uploaded it. I received an error code saying that an element must be closed with ">" or "/>" which i know, however I closed the element and it still isn't validating. here is the code:

<div class='post-author'>
    <h4 class='block-heading'><span>About the Author</span></h4>
    <div class='author-img'>
        <img alt='' class='avatar avatar-110 photo' height='110' src='https://www.flickr.com/photos/34847437@N02/16125062891/ width='110'/>
    </div>
    <div class='author-text'>
        <h4><a href='' rel='author' title=''>Emilie Jay</a></h4>

        <span class='author-share'>
            <a href='https://twitter.com/unfoundclovers'><i class='fa fa-twitter round-icon'/></a>                  
            <a href='http://instagram.com/unfoundclovers'><i class='fa fa-instagram round-icon'/></a>       

            <a href='http://www.pinterest.com/unfoundclovers/'><i class='fa fa-pinterest round-icon'/></a>                                  
        </span>
    </div>
</div>

and the error is appearing in the 4th line beginning with the tag. It looks properly closed but like I said, isn't validating. Can anyone help?
