I actually tried to incorporate this code

https://imageurl.com/img.jpg
<center> **left image caption** </center>
</div>

into mine, to put captions at the bottom of each image. It won't work inside the div tag.....I'm playing around with nested div's but no luck so far....I'm just learning this stuff but it fascinates me!
As far as CSS code...phffffft! It doesn't work here or I should say ,it doesn't work as expected here.....I sure wish we could change font colors and styles. I'm looking for work arounds.
CARRY ON!
