Is this your theme? http://demo.wpweaver.info/

If yes, open
wp-content/uploads/weaver-subthemes/style-weaver.css

search for #primary and add your border-left:16px solid yellow; like the code above.

Also the above code won’t work because you have a closing </style> tag in the beginning. It should be:

<style>
#branding img{margin-top: 0px;}
#wrapper {margin-top: 0px;}
#primary {border-left:16px solid yellow;}
</style>

I don’t think there is a WordPress function for that but I use this function to get the first image from the post content:

function get_first_image() {
    global $post;
    $first_image = '';
    ob_start();
    ob_end_clean();
    $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
    $first_image = $matches[1][0];

    if(empty($first_image)){ //return false if no image is found
        $first_image = false;
    }

    return $first_image;
}

Yes maybe you are pasting the code on the Visual tab of the editor. Paste it on the HTML tab. Tabs are located at the upper right corner of the content editor.

I am not familiar with the Weaver theme so maybe you can try asking on their forum if they have one. I’m sure someone there will be willing to help you. Or wait for someone here who knows the theme, because without looking at your website I won’t be of much help. Goodluck! 🙂

You could use faux columns technique for the border: http://www.alistapart.com/articles/fauxcolumns/

(can’t believe I can still reference to that article after 7 years)

Hi,

It could be that your caching plugin is disabled for admins and/or registered users.

To help identify the problem try setting WP_DEBUG to TRUE, found in wp-config.php.

If you can’t find any other solution you can just remove the transparency and make it a blue background, same as the header background color.
