=== Frequently Asked Questions ===
How can I change the WordPress login logo without a plugin?
Add a small function to functions.php or, better, use a code snippets tool (like WPCodeBox) so you don’t edit the theme. You’ll enqueue CSS that sets #login h1 a { background-image:url(...); } and adjust background-size/width/height. This keeps changes update-safe and portable.
What size should my WordPress login logo be?
There’s no hard rule, use a clear, horizontal logo and scale it with CSS (e.g., ~300–400px wide) for a crisp look across screens. Many guides suggest preparing a wider raster (e.g., 720×144) and letting CSS scale it down for HiDPI.
How do I change the WordPress login logo link (so it goes to my homepage)?
Use the login_headerurl filter to return home_url('/').
Can I customize more than the logo (colors/background) on the login page?
Yes, update the login form styles via CSS (backgrounds, inputs, buttons).
