Add post order to function (php) - php

Question

How to add post order to this function? I would like to display most recent post from newest to oldest:
<?php
//Establish first post check variable
$first_post = true;
query_posts('category_name=blog&showposts=3');
while (have_posts()) : the_post(); ?>
<li>
<a href="<?php echo get_permalink($post->ID); ?>">
<p class="news_title"><?php $title = get_the_title(); echo wp_trim_words( $title , '4', $more = null ); ?></p></a>
<?php if($first_post) { ?>
<div class="post_skrot"><?php echo wp_trim_words( get_the_content(), $num_words = 8, $more = '... <a class="button_more" href="'. get_permalink($post->ID) . '">show more >> </a>' ); ?></div>
<?php } else { ?>
<div class="post_skrot"><a class="button_more" href="'.get_permalink($post->ID).'">show more>> </a></div>
<?php } ?>
</li>
<?php
//Change value of $first_post
$first_post = false;
endwhile;
wp_reset_query(); ?>
I try add
&orderby=date&order=ASC
but it doesn't work.
Whole code:
<div id="sliders-2-3">
<div class="elementy-oferty">
<div class="slider-4">
<div class="border-video">
<div class="content-slider-4">
<div class="blog_top_title">Blog</div>
<ul>
<?php
//Establish first post check variable
$first_post = true;
$args = array(
'posts_per_page' => 3,
'cat' => 317,
'orderby' => 'DESC'
);
$the_query = new WP_Query( $args );
?>
<?php if ( have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<div class="blog_post_sekcja">
<a href="<?php echo get_permalink($post->ID); ?>">
<p class="news_title"><?php $title = get_the_title(); echo wp_trim_words( $title , '4', $more = null ); ?></p></a>
<?php if($first_post) { ?>
<div class="post_skrot"><?php echo wp_trim_words( get_the_content(), $num_words = 30, $more = '... <a class="button_more" href="'. get_permalink($post->ID) . '">pokaż więcej » </a>' ); ?></div>
<?php } else { ?>
<div class="post_skrot"><a class="button_more" href="<?php echo get_permalink($post->ID); ?>">pokaż więcej » </a></div>
<?php } ?>
</div>
<?php
//Change value of $first_post
$first_post = false;
endwhile;
wp_reset_query(); ?>
</ul>
<div class="blog_more">
Więcej wpisów</div>
</div>
</div>
</div>
I've got: Parse error: syntax error, unexpected end of file...on line 145. 145 is my last line in code and on this line I have only <?php get_footer(); ?>
I think it must be something with endwhile; or another syntax.

Your $args array is off a little bit. Should be:
<div id="sliders-2-3">
<div class="elementy-oferty">
<div class="slider-4">
<div class="border-video">
<div class="content-slider-4">
<div class="blog_top_title">Blog</div>
<ul>
<?php
//Establish first post check variable
$first_post = true;
$args = array(
'posts_per_page' => 3,
'cat' => 317,
'orderby' => 'date',
'order' => 'DESC' // or 'ASC like in your original code.'
);
$the_query = new WP_Query( $args );
if ( have_posts() ) {
while ( $the_query->have_posts() ) {
$the_query->the_post(); ?>
<div class="blog_post_sekcja">
<a href="<?php echo get_permalink($post->ID); ?>">
<p class="news_title"><?php $title = get_the_title(); echo wp_trim_words( $title , '4', $more = null ); ?></p></a>
<?php if ( $first_post ) : ?>
<div class="post_skrot"><?php echo wp_trim_words( get_the_content(), $num_words = 30, $more = '... <a class="button_more" href="'. get_permalink($post->ID) . '">pokaż więcej » </a>' ); ?></div>
<?php else : ?>
<div class="post_skrot"><a class="button_more" href="<?php echo get_permalink($post->ID); ?>">pokaż więcej » </a></div>
<?php endif; ?>
</div>
<?php
$first_post = false;
}
}
wp_reset_postdata();
?>
</ul>
<div class="blog_more">
Więcej wpisów</div>
</div>
</div>
</div>
