How do I display my RSS feed horizontally?
javascript html css
I want to display my custom RSS feed as a horizontal list. I am using a responsive template and embedding my feeds into that template. I believe that my JavaScript is not separating each RSS post into a separate list item like I thought it would.
(function($) {
"use strict";
var RSS = function(target, url, options, callback) {
this.target = target
this.url = url
this.html = []
this.effectQueue = []
this.options = $.extend({
ssl: false,
limit: null,
key: null,
layoutTemplate: ‘<ul style="display:inline-block;">{entries}</ul>’,
entryTemplate: ‘<li><a href="{url}"><div class="title">{title}</div></a><br /><author>{author}</author><img src="{teaserImageUrl}"></img><date>{date}</date><br />{shortBodyPlain}</li>’,
tokens: {
},
outputMode: ‘json’,
dateFormat: ‘MMM Do, YYYY’,
effect: ‘show’,
offsetStart: false,
offsetEnd: false,
error: function() {
console.log("jQuery RSS: url doesn’t link to RSS-Feed");
},
onData: function(){},
success: function(){}
}, options || {})
this.callback = callback || this.options.success
}
RSS.htmlTags = ["doctype", "html", "head", "title", "base", "link", "meta", "style", "script", "noscript", "body", "article", "nav", "aside", "section", "header", "footer", "h1-h6", "hgroup", "address", "p", "hr", "pre", "blockquote", "ol", "ul", "li", "dl", "dt", "dd", "figure", "figcaption", "div", "table", "caption", "thead", "tbody", "tfoot", "tr", "th", "td", "col", "colgroup", "form", "fieldset", "legend", "label", "input", "button", "select", "datalist", "optgroup", "option", "textarea", "keygen", "output", "progress", "meter", "details", "summary", "command", "menu", "del", "ins", "img", "iframe", "embed", "object", "param", "video", "audio", "source", "canvas", "track", "map", "area", "a", "em", "strong", "i", "b", "u", "s", "small", "abbr", "q", "cite", "dfn", "sub", "sup", "time", "code", "kbd", "samp", "var", "mark", "bdi", "bdo", "ruby", "rt", "rp", "span", "br", "wbr"]

}
$.fn.rss = function(url, options, callback) {
new RSS(this, url, options, callback).render()
return this; //implement chaining
}
})(jQuery)
When I view the page source, there is not dynamically created html. How would I display these list items inline?
The feeds appear in HTML as follows:
<script>
jQuery(function($) {
$("#rss-feeds").rss("http://www.feed43.com/channelfireball.xml", {
limit: 15
})
</script>
<div style="border:none;width:100%;height:auto;overflow-y:scroll;
overflow-x:scroll;">
<div class="span2 item">
<div class="item-wrap">
<div class="post_results" id="rss-feeds"></div>
</div>
</div>
</div>

Try applying style: ul { display: inline-block; } – Roberto Apr 27 ’15 at 20:40
Thank you for the response. I’ve attempted to add this in as many ways and places as I could find. I am able to add some styles to the dynamically created HTML, but have been unable to add this change to the list. If it helps, I am able to change the tags in my JavaScript to anything and achieve the same results. For instance, I could use <water></water> instead of <ul></ul> and get the same output on my webpage. – Geremiah Holbrook Apr 28 ’15 at 21:55
have you tried adding the styles as you create the layoutTemplate, using the style attribute to apply the styles that Robert suggests? adding inline-styles may cause problems down the line with style inheritance though. – Dpeif Apr 29 ’15 at 9:19
Can you provide mode code? it is not really clear. Thanks – Nick Apr 29 ’15 at 9:19
