After pasting it, click **Publish**, then check your phone again. Also clear any cache if you are using a caching plugin.

One important note: **CSS can fix sizing, spacing, wrapping, and stacking**, but it cannot fully create a working hamburger menu if your theme does not already have one. If your menu still looks bad after this, the next thing to adjust is your theme’s **mobile header/menu settings**.
