How to re-size text content on class="item-thumbnail-left item-icon-right"?

Hello there,

I’m using class=“item-thumbnail-left item-icon-right” on an item but I would like to see my textContent bigger than the default one.
How can I do that?

Thanks for helping me,
Best Regards.

I’ve just solved this feature by using this.

                    <img src="image Path" width="80px" style="margin-left: -25px"/>
                </div>
                <div class="col" style="margin-left: 10px">
                    <h2 style="font-size: 0.6em; overflow:inherit;">TEXT</h2>
                    <h2 style="font-size: 0.6em; overflow:inherit;">TEXT</h2>
                    <h2 style="font-size: 0.6em; overflow:inherit;">TEXT</h2>
                    <h2 style="font-size: 0.6em; overflow:inherit;">TEXT</h2>

                </div>
                <div class="col col-20">
                        <li class="ion ICON" style="margin-top: 35%;  font-size:40px; margin-left: 50%"></li>
                </div>
            </div>
        </div>
    </div>

And the result is:
