How to give border bottom to heading with font awesome icon - html

Question

In my first div container, I added a heading 1 tag, gave a border bottom a color of my desire, and added font awesome icon in the middle.
As you can see I had to give a background color on the font awesome to make it appear transparent. but now I have a background image on the second box so I am struggling to achieve the same thing.
How can I do the same on my other div box without affecting the background image
visibility as well as the border bottom from the heading 1?
div.container{
background-image: url(http://az616578.vo.msecnd.net/files/2016/04/09/6359580807140768861266757027_Never-Study-Hard-The-Art-of-Studying-Smart.jpg);
background-size: cover;
background-position: 50%;
}
div{
height: 100px;
}
h1.widget_title_1{
font-size: 25pt;
display: inline-block;
margin: 0;
margin-top: 35px;
padding-bottom: 9px;
border-bottom: 1px solid #898989;
position: relative;
}
h1.widget_title_1:after {
position: absolute;
font-family: fontawesome;
display: block;
margin-left: 58px;
margin-top: -7px;
padding: 0 5px;
font-size: 24pt;
color: black;
content: '\f107';
font-weight: 300;
background-color: white;
}

Answer 1

I suggest you to use font-awesome icons along-with tag as here I have used i tag, it get's easy to align icon i.e. at center of that div tag, just by using text-align:center. Then you can use pseudo selector :before and :after on h1 tag and add that border. Scale to and fro on this jsFiddle and see border doesn't get's attached at certain screen resolution.
.container-1 {

}

Use :before :after for div for the line.
Create a span tag with the font awesome as shown below.
div.container{
background-image: url(http://az616578.vo.msecnd.net/files/2016/04/09/6359580807140768861266757027_Never-Study-Hard-The-Art-of-Studying-Smart.jpg);
background-size: cover;
background-position: 50%;
}
div{
position: relative;
height: 100px;
}
h1.widget_title_1{
font-size: 25pt;
display: inline-block;
margin: 0;
margin-top: 35px;
padding-bottom: 9px;
border-bottom: 1px solid #898989;
position: relative;
}
span:after {
position: absolute;
font-family: fontawesome;
display: block;
margin-left: 58px;
margin-top: -7px;
top:40px;
padding: 0 5px;
font-size: 24pt;
color: black;
content: '\f107';
font-weight: 300;
background-color: transparent;
}
div.container:after{
content: "";
position: absolute;
height: 5px;
border-bottom: 1px solid black;
top: 45px;
width: 60px;
}
div.container:before{
content: "";
position: absolute;
height: 5px;
border-bottom: 1px solid black;
top: 45px;
left:90px;
width: 60px;
}
