Astra Theme version 3.6.3 brought changes to default padding values for buttons to improve the default UI. Furthermore, this update came with the fix for Global padding settings not being applied to Gutenberg buttons.
Why Do I Need This Improvement?
Previously, the theme default button padding values were 10px on top and bottom and 40px on the left and right sides. These settings negatively influenced the visual appeal of the buttons as they made buttons too wide.
That』s why we updated these values to 15-30px (top, bottom – right, left).
Also, if you used Gutenberg for your posts or pages, you might have noticed that the button padding values you set at Customizer > Global > Buttons didn』t apply and that you needed to set these values manually for each button.
Though these things were changed with Astra 3.6.3 update, this won』t be applied automatically to your website to avoid any adverse effects on your existing websites.
How To Fix This?
For all new websites, these changes will be applied automatically.
As mentioned, for the existing website, this improvement needs to be activated by adding a filter. This was done to allow you to check how these changes apply to your website and make any changes if needed.
To apply the improvement to your existing website, you would need to add a filter to the functions.php file of your Child Theme. If you don』t have your Child Theme installed, please check this article on how to do it. Please add the following filter:
add_filter( 'astra_update_button_padding_defaults', '__return_true' );
