Help with a Placing 2 images side by side in PHP

I am having trouble putting these 2 images side by side:

<img src="<?php echo get_template_directory_uri(); ?>/images/paypal.gif"/>
<img src="<?php echo get_template_directory_uri(); ?>/images/Steps2.png"/>

HTML Code:

---

<img class="floatLeft" src="<?php echo get_template_directory_uri(); ?>/images/paypal.gif"/>
<img class="floatLeft" src="<?php echo get_template_directory_uri(); ?>/images/Steps2.png"/>

---

HTML Code:

---

<style>
.floatLeft {
float: left;
}
</style>
