I have an html css code in

https://jsfiddle.net/zakutrp4/

the output style above <div style='height:1em'></div> line is what I want

for some reason I need to add link<a></a> outside the <img> but the output style below <div style='height:1em'></div> is not what I want. I want the output style is like that above <div style='height:1em'></div>. I want to know how to change the source code? Maybe add some style in <a>. Can somebody figure out how to solve the problem?

soure code:

<link rel='stylesheet' href='https://fonts.googleapis.com/icon?family=Material+Icons'>
