Category cloud can be added by using the taxonomy argument to cause a cloud of categories to display. You can either modify wp-content/yourtheme/single.php from ssh or using ftp OR you can login to wordpress dashboard, and go to “Appearance -> Editor -> ad click “single.php”
Post below line,
[php] <?php wp_tag_cloud( array( ‘taxonomy’ => ‘category’ ) ); ?> [/php]After,
[php] <div class="thecontent"> <?php the_content(); ?> </div> [/php]So, the final change could look like as below,
To update into single page, modify the page.php as above.
If we want to customise the look of default Category cloud, we can modify the following code from wp-includes/category-template.php to add a border , and fill the color with boxed looks as below,
[php] // Generate the output links array. foreach ( $tags_data as $key => $tag_data ) { $class = $tag_data[‘class’] . ‘ tag-link-position-‘ . ( $key + 1 ); $a[] = sprintf( ‘<a href="%1$s"%2$s class="%3$s" style="font-size: %4$s; color: #fff; border: 1px solid; margin: 1px 1px; display: inline-block; padding: 5px 5px; background-color: #777;"%5$s>%6$s%7$s</a>’, ); } [/php]Reference – https://codex.wordpress.org/Function_Reference/wp_tag_cloud#Display_a_Category_Cloud
