Columns > Tables
It's important to format and organize images, text, and links on a page so they are responsive. Tables built in the WYSIWYG editor are not responsive and will not display properly as your site reformats for smaller screen resolutions (ie: small laptops, tablets, and phones).
PRO-TIP: You can use responsive columns, which function similarly to tables but will adjust to the screen size being viewed.
Grid layouts are handy when many calls to action are needed on one page. You may want to create a grid layout for your Ministries, Sunday School Classes, or even your Next Steps. With a little patience and some help from the Ekklesia 360 Tools site, you can use the Responsive Grids Tool to generate a custom layout.
