How to Fix: Invalid Twitter Card

Sometimes when you share a RebelMouse article to Twitter, it will render the tweet without a Card:


Tweets are usually accompanied by a Twitter Card, which features a preview image and rendered text like in the following example:

If you don't see a Twitter Card, we recommend double-checking the issue using Twitter's Card validator tool. After you paste in the URL to your post and perform a check, you'll likely see it come up as invalid because of a long response time, which means there's too much HTML:

The solution for this problem is to create a B-test layout, and then lazy load every element possible on the page. Then, recheck the URL using Twitter's validator tool until it resolves as fixed.

Here are some articles on our lazy loading features:

How to Use Variables to Set Colors Across Your Site

Why This Is Important

You can easily set colors for every element of your site on RebelMouse, including the color of your text, links, and headlines. Usually there's a set of 2–3 colors used across a site. But instead of hardcoding the color on every element, you can use variables to make it so that if a color needs to change, you can update it in one place instead of everywhere — making future maintenance easy.

Learn More About RebelMouse’s High-Performing Infrastructure

To ensure every site powered by RebelMouse is high performing, secure, and optimized for user experience, we only use the best and most reliable methods to host our infrastructure. Here's a detailed look at some of the services and security measures we use every day to secure maximum stability and security for each of our sites.

Click here to learn more about what makes RebelMouse secure, stable, redundant, and high performing.

Services

Stateless services, such as application services for front end and back end tasks, are deployed within an Amazon Virtual Private Cloud (VPC) into multiple availability zones using Amazon Auto Scaling groups. Every service deployment is automated and can be done without an operator. Auto Scaling groups eliminate the need for manual recovery procedures in the event of hardware-related incidents. Additionally, Auto Scaling groups for stateless services provide the ability to balance resources according to current load.

Stateless services include:

  • Front end and back end applications
  • Background workers
  • Dedicated services for paid content and statistics

All interactions with our internal services are done via Amazon Elastic Load Balancing (ELB). Load balancing allow us to control the flow of all incoming traffic and reroute it to the group of instances that are available as necessary, which covers any networking and hardware issues. Every load balancer controls the health of the listener instance by regularly performing health checks and removing failed instances from production environments.

Load balancing and Elastic Compute Cloud (EC2) instances provide monitoring services with resource consumption data. Stateful services such as MongoDB, Redis, and Memcached are deployed within a VPC into multiple availability zones using Auto Scaling groups. Every data service has backup, recovery, and automatic failover procedures. Backup and recovery procedures are integrated into Auto Scaling groups and tested regularly.

Services performance is monitored by internal and external tools:

  • Sentry is used to track errors.
  • New Relic is used for application performance monitoring.
  • Amazon CloudWatch is used to monitor performance extremes.
  • Monit, Nagios, and Cacti are used to monitor metrics per instance.

Security

Defense in Depth (DiD) standards are adhered to and applied at all levels:

  • Amazon Web Services (AWS), such as Identity and Access Management (IAM), and CloudTrail
  • VPC and subnets
  • Load balancers (security groups)
  • EC2 instances
  • Operating systems use permissions-based controls

Access Monitoring:

  • AWS CloudTrail monitors all activities in our production data centers and grants us the ability to perform audits

Data Protection:

  • Secured storage
  • Encrypted transition protocols

When to Use the Post Content Element’s Lead Media Properties

RebelMouse's Layout & Design tool makes designing your site easy and intuitive. But there are certain design factors you need to take into account when building out your site.

When creating a post page (i.e., the landing page for any article that a user is directed or navigates to), styling it is slightly different from other pages because it requires you to use the Lead Media property of a Post Content element. Within the context of our Layout & Design tool, "Lead Media" is defined as the main post tied to a post page's URL, which includes all of its images, media, and text.

By contrast, the Posts element displays all other articles (or posts) that aren't the main post you land on. These are the subsequent posts on a page that appear afterward as you scroll — such as in an infinite scroll setup, for example.

We now have a new feature that will be very helpful for clients that have multiple sites and/or a site network powered by RebelMouse: Cross-Site Shareable Elements. This new feature makes styling work much easier since users are able to update several site layouts at once by editing a single element. This should also prevent duplicating code in similar site layouts, as well as saving users some coding time.
