I am creating my own custom theme from scratch and have run into a bit of trouble. On the blog page, each time a new post is displayed, it is smaller than the last. This is due to me setting the width of the blog post to 33.3%. Also each blogpost gets displayed slightly right of the one previous to it. How can I have each blog post be 33.3% of the content area and be displayed side by side, 3 per row? I am using wordpress functions to call each blog post. I am only displaying the blog posts thumbnail and when you click the thumbnail it takes you to the post. So basically 3 images side by side.
[BONUS]: How could I get text to display horizontally and vertically on hover over each blog post image?
I know this is a lot to ask, but I have been trying to work this out for days. A JS Fiddle or Codepen would be greatly appreciated.
Index.php:
<?php get_header(); ?>
<div class="blog-posts">
<?php while (have_posts()) : the_post(); ?>
<div id="page-content">
<a href="<?php the_permalink(); ?>">
<?php the_post_thumbnail(); ?>
<h3><?php the_title(); ?></h3>
</a>
<?php endwhile; ?>
</div>
</div>
<?php get_footer(); ?>
