rss-ticker is a custom HTML element which displays an RSS/Atom feed feed as a sequence of items which repeatedly scrolls horizontally to show all items. Using the mouse or touch, an rss-ticker can be controlled by dragging. To temporarily halt the ticker and show an infobox with full content, or to let it scroll forwards and backwards at different speeds.\
The items are displayed in a color that is dependent on the item's publication date. By default, a "new" item is displayed in red and an "old" item is displayed in blue. Less new and less old items are displayed with a color inbetween red and blue. Attributes can be set to change these colors and to specify when an item is "new" or "old". Changing the value of most of the attributes is immediately effective.
See this page for a demonstration.
Page johnerps.com#d also has an rss-ticker. Click on the yellow circle with the RSS icon (bottom half, right of the screen) to open a form in which the ticker's attributes can be changed, while it's running. Experiment with rss-ticker attributes. See effects immediately.
rss-ticker is simple to use. Add it to a page like any other element, set it's attributes, add some styling. No Javascript needed.
For example, the following html code adds an rss-ticker.
<rss-ticker autostart="2" url="http://rss.cnn.com/rss/edition.rss"></rss-ticker>
It automatically starts 2 seconds after being attached to the DOM. It fetches RSS/Atom feed http://rss.cnn.com/rss/edition.rss.
It happens that a feed can not be fetched due to, for example, CORS restrictions. Attribute proxy-url is used to fetch the feed through another server (for example the one that served the page) to mitigate the restrictions.
The demo page has two rss-tickers which are added to the page with the following html (and some styling).
<rss-ticker id="rss1"
url="http://rss.cnn.com/rss/edition.rss"
proxy-url="https://johnerps.com/php/getfile.php?url=%%_URL_%%"
autostart="3"
speed="2.5"
color-new="#a44"
color-old="#bbb"
hrs-old="6"
transparency="0.3"
infobox-link-bgcolor="#1a1a1a"
font-size="1.3"
></rss-ticker>
<rss-ticker id="rss2"
url="https://www.theguardian.com/uk/rss"
proxy-url="https://johnerps.com/php/getfile.php?url=%%_URL_%%"
autostart="5"
speed="4"
infobox-img-size="3"
color-new="#888"
color-old="#333"
transparency="0.3"
infobox-link-color="#1a1a1a"
infobox-link-bgcolor="#b0b0b0"
></rss-ticker>
The page with the <rss-ticker> element(s) must have modules webcomponentsjs (for browser compatibility) and rss-ticker added to the <head> element.
<head>
.
.
<script src="https://unpkg.com/@webcomponents/webcomponentsjs"></script>
<script src="https://unpkg.com/rss-ticker"></script>
</head>
