    In general to change the color on a span you can use

    var element = document.getElementById('RelevantDiv');
    element.style.background = '#FFFFFF';
    

    I assume,you want to target the span and not the whole div thus, put the id on span like this

    <span id="RelevantDiv" style="background-color: red">
    

    Now to wrap it up in a function you wrote it correctly in the code provided but you need to call that function usually by using an event handler if you want to call it at certain times.

    Here is a jsfiddle for calling the function when you mouse over the span.

    Your background-color is on the span element while in the js your are targetting the parent div.

    Try the following :

    var element = document.querySelectorAll('#RelevantDiv > span')[0];
    element.style['background-color'] = '#FFFFFF';
    

    Although, I suggest you to give a class name to your highlighted span, and select by that class and not by the tag name.

    You're pointing at the div, not the span so the css isn't overridden. Try this:

    <div id="RelevantDiv">the industry's standard <span id='span_id' style="background-color: red">...
    

    Then change the function

     function HLtoggle()
    {
        var element = document.getElementById('span_id');
        element.style.backgroundColor = '#FFFFFF';
    }
    HLtoggle()

    A CSS selector is the first part of a CSS Rule. It is a pattern of elements and other terms that tell the browser which HTML elements should be selected to have the CSS property values inside the rule applied to them.

    Instead of using !important, consider: Make better use of the CSS cascade Use more specific rules. By indicating one or more elements before the element you're selecting, the rule becomes more As a nonsense special case for (2), duplicate simple selectors to increase specificity when you have

    CSS selectors are used to "find" (or select) the HTML elements you want to style. We can divide CSS selectors into five categories: Simple selectors (select elements based on name, id, class) Combinator selectors (select elements based on a specific relationship between them)

    Both inline styles and !important are considered very bad practice, but global CSS file as !important, thus overriding inline styles set directly on elements. Without !important , the first rule will have more specificity and will

    That’s why CSS resets are so handy. A CSS reset allows you to apply styles to certain HTML tags to bring their values back to the default. Think of a CSS reset as a way to override a browser’s default styles.

    You should set the class in your css file so it is distributed to all elements that have that class console.log($('.redclass').length) $("p").addClass("redclass"); console.log($('.redclass').length) // $(".redclass").css("color", "darkRed"); $("span").addClass("redclass"); console.log($('.redclass').length)

    Inline CSS or Internal CSS In writing code for web, HTML and CSS are the foremost basic combination. HTML provides the structure while CSS fills out to represent them in a specific way. There are three different ways for writing CSS for HTML Internal, External and inline CSS.

    An !important declaration provides a way for a stylesheet author to give a CSS value more weight than it naturally has. Syntax and Description It should be noted here that the phrase “!important declaration” is a reference to an entire CSS declaration, including property and value, with !important added (thanks to Brad Czerniak for pointing out this discrepancy).
