WordPress - how to get posts content and title - php

Question

I am new to WordPress and I need to retrieve the content and title of all the posts but can't find my way. here is my code.
require_once("blog/wp-load.php");
$the_query = new WP_Query( ['posts_per_page' = -1]);
if ( $the_query->have_posts() ) {
while ( $the_query->have_posts() ) {
$the_query->the_post();
$a= $the_query->post_content;
echo $a;
}
wp_reset_postdata();
}
It is giving me a blank page

Once the loop has the posts in storage you can use other methods to get information about the posts.
Example for a card holding an image, title of a piece of content, etc.
<section>
<div class="container">
<div class="card">
<div class="row">
<div class="col-md-6">
<a href='<?php the_permalink();?>'>
<div class="card-img-bottom" style=' height:100%;background-image: url(<?php the_post_thumbnail_url( 'full' ); ?>);background-size:cover;'>
</div>
</a>
</div>
<div class="col-md-6">
<div class="card-block">
<h2><?php the_title(); ?></h2>
<p class="card-text"><?php the_excerpt(); ?></p>

</div>
</div>
</div>
</div>
</div>
</section>
Each post being returned by the loop would then be embedded in that context (HTML/CSS)
At the bottom of your page above a footer call you can also end the loop like this:
<?php endwhile; else : ?>
<?php endif; ?>
Also to specify. You can obtain the content with
the_content();
The title with
the_title();
And the link to the post with
the_permalink();
