Hi Manjim,
To change the width of the left sidebar in left sidebar blog you should edit the index.php, the edited version of the index.php is attached below with smaller sidebar.
and for another query, we don’t understand about the problem fully, so could you please explain more and it will be better if you provide the link of the site.
<?php $blogstyle = get_theme_mod( 'blog_style', 'blogright' );
switch ($blogstyle) {
// Right Column
case "blogright" :
echo '';
// get all the posts
if ( have_posts() ) : while ( have_posts() ) : the_post();
// get the article layout
get_template_part( 'content', get_post_format() );
endwhile;
// get the pagination
flat_responsive_paging_nav();
else :
// if no posts
get_template_part( 'content', 'none' );
endif;
echo '
';
break;
// Left Column
case "blogleft" :
echo '';
echo '
';
if ( have_posts() ) : while ( have_posts() ) : the_post();
get_template_part( 'content', get_post_format() );
endwhile;
flat_responsive_paging_nav();
else :
get_template_part( 'content', 'none' );
endif;
echo '
';
break;
// Left and Right Column
case "blogleftright" :
echo '';
echo '
';
if ( have_posts() ) : while ( have_posts() ) : the_post();
get_template_part( 'content', get_post_format() );
endwhile;
flat_responsive_paging_nav();
else :
get_template_part( 'content', 'none' );
endif;
echo '
';
break;
// Wide Column
case "blogwide" :
echo '';
if ( have_posts() ) : while ( have_posts() ) : the_post();
get_template_part( 'content', get_post_format() );
endwhile;
flat_responsive_paging_nav();
else :
get_template_part( 'content', 'none' );
endif;
echo '
';
break;
}
?>
Thanks
