In August 2017 we announced that Moments would render as timelines instead of grids. Today, we’re announcing the end of our support for grid-style embedded collections. We want to focus on widget types which are more widely adopted, such as embedded Tweets and timelines. We’ll continue to support embedded grids for 30 days, and after that point, all grid-style collections will render as timelines.
This change will only impact embedded collections in the grid style (with
class="twitter-grid"). You can update your collections to the timeline display format today by changing
class="twitter-timeline" in your embed code. After February 8, 2019, your grid embeds will automatically render as timelines.
Please post in the Twitter for Websites forum if you have any questions about the upcoming change.
