Custom Login Page Styling

The default WordPress login page shows the WordPress logo and generic styling. This snippet lets you brand it with your own logo, colors, and styles for a professional appearance.

Add to your functions.php

// Custom login page styles
function custom_login_styles() {
    $logo_url = get_template_directory_uri() . '/images/logo.png';
    ?>
    <style>
        body.login {
            background-color: #f5f5f5;
        }
        #login h1 a {
            background-image: url('<?php echo esc_url($logo_url); ?>');
            background-size: contain;
            background-repeat: no-repeat;
            background-position: center;
            width: 100%;
            height: 80px;
        }
        .login form {
            border-radius: 8px;
            box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1);
        }
        .login #backtoblog a,
        .login #nav a {
            color: #333;
        }
        .login #backtoblog a:hover,
        .login #nav a:hover {
            color: #0073aa;
        }
        .wp-core-ui .button-primary {
            background-color: #0073aa;
            border-color: #006799;
            border-radius: 4px;
        }
        .wp-core-ui .button-primary:hover {
            background-color: #006799;
        }
    </style>
    <?php
}
add_action('login_enqueue_scripts', 'custom_login_styles');

// Change login logo URL to homepage
function custom_login_logo_url() {
    return home_url('/');
}
add_filter('login_headerurl', 'custom_login_logo_url');

// Change login logo hover title
function custom_login_logo_title() {
    return get_bloginfo('name');
}
add_filter('login_headertext', 'custom_login_logo_title');

What this does

• login_enqueue_scripts – Injects custom CSS into the login page
• login_headerurl – Changes the logo link from wordpress.org to your homepage
• login_headertext – Changes the logo hover text to your site name

Note: Replace /images/logo.png with the actual path to your logo file in your theme directory.
