Here, you are going to learn how to create a customized look for announcements web part like the below sample.

Here are the features of this web part.

Displays only the active announcements in an order.
Only minimal and important details are displayed in the web part. The rest of the details are displayed in a modal pop up.
Displays only five items in the web part and “view all” link will redirect to the announcement list view which is created to display only the active announcement
The modal popup will be displayed when the announcement title is clicked in the web part.

Steps to create the announcement web part using Javascript

Create an announcements list and add the fields which you want (In this case, the below are my columns).
Once the list is created, add some new announcements (the code will display only the active announcements).
Post adding the announcements, create a new view for displaying only the active announcement. For this, you can use the “expires” column to extract only the active announcement. While creating a view, filter the item by using the below condition and sort the “expires” column by ascending order , so that the web part will display the announcement in an order.
Once the view is created, you are ready to code the announcement list to get the data and display it in the page wherever you want.
Add the content editor/ script editor web part to place out SP script in order to get the data from the announcement list view.
Place the below code in the script editor and save the page, after configuring the list name, view name, site collection, and site URL, save the page. If everything is configured as mentioned, you will get the same announcement view with rich look and feel like “figure 1”.
