如何覆盖默认"自然" WordPress中缩略图的大小?我的functions.php和CSS无效。它使图像模糊。
的functions.php
// Enable support for Post Thumbnails on posts and pages.
add_theme_support('post-thumbnails');
set_post_thumbnail_size( 450, 250, true );
Style.css:
/* Featured image thumbnail */
.attachment-post-thumbnail, .size-post-thumbnail, .wp-post-image {
width: 450px !important;
height: 250px !important;
}
Page-blog.php(自定义博客页面):
<article id="post-<?php the_ID(); ?>"
<?php post_class(); ?>>
<h2 class="">
<a class="blog-title" href="<?php the_permalink(); ?>"> <?php the_title(); ?></a> </h2>
<div class="entry-content"> <?php
if ( has_post_thumbnail ) {
the_post_thumbnail();
}
the_excerpt();
?>
</div>
</article>
在 Google Dev Tools 中, HTML呈现如下所示。请注意,它附加了默认的150 x 150(我没有用这种方式进行硬编码):
<div class="entry-content">
<img width="150" height="150" src="http://localhost:8888/wordpress/wp-content/uploads/2018/02/feature_nothavingit-150x150.jpg" class="attachment-post-thumbnail size-post-thumbnail wp-post-image" alt="" srcset="http://localhost:8888/wordpress/wp-content/uploads/2018/02/feature_nothavingit-150x150.jpg 150w, http://localhost:8888/wordpress/wp-content/uploads/2018/02/feature_nothavingit-45x45.jpg 45w" sizes="(max-width: 150px) 100vw, 150px">

更好的做法是通过方法get_the_post_thumbnail_url()使用缩略图的网址。您只需使用下一个结构,就可以制作任何自定义缩略图。确保您拥有所需分辨率的附加图像。要正确处理所有分辨率,最佳做法是使用<picture></picture>
选择器。
$thumbnail_url = get_the_post_thumbnail_url(the_ID(), 'post-thumbnails');
<div class="entry-content">
<img src='<?php echo $thumbnail_url; ?>'>
</div>
