我正在使用Twenty Seventeen主题并试图在Google Page Speed测试中取得好成绩 . 我正面临着二十七主题的style.css的“ Eliminate render-blocking JavaScript and CSS in above-the-fold " and " Leverage browser caching ”问题 .
我尝试使用.htaccess文件消除此问题，但仍然遇到同样的问题 .
这是我的.htaccess文件：
# WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
ExpiresActive On
ExpiresByType image/gif A2592000
ExpiresByType image/jpeg A2592000
ExpiresByType image/jpg A2592000
ExpiresByType image/png A2592000
ExpiresByType image/x-icon A2592000
ExpiresByType text/css A86400
ExpiresByType text/javascript A86400
ExpiresByType application/x-shockwave-flash A2592000
#
<FilesMatch "\.(gif¦jpe?g¦png¦ico¦css¦js¦swf)$">
Header set Cache-Control "public"
</FilesMatch>
我不想使用任何优化插件或缓存插件 .
为了修复js文件的“ Eliminate render-blocking JavaScript and CSS in above-the-fold ”，我在function.php文件中添加了一个代码 .
这是代码：
function defer_parsing_of_js ( $url ) {
if ( FALSE === strpos( $url, '.js' ) ) return $url;
if ( strpos( $url, 'jquery.js' ) ) return $url;
return "$url' async defer='defer";
}
add_filter( 'clean_url', 'defer_parsing_of_js', 11, 1 );
谁能建议我在不使用插件的情况下修复此问题？
