How to match all elements having class name starting with a specific string

In CSS, if you want to select elements whose class names start with a specific string, you can use attribute selectors with a specific matching pattern. This pattern is ^=, which is used to select elements where the attribute value begins with the specified content.

For example, if you want to select elements whose class names start with intro, your CSS rule would be:

css
[class^="intro"] {
    /* CSS styles */
}

In this example, any element whose class attribute value starts with intro will be selected and have the CSS styles defined here applied.

Note that the class attribute may contain multiple values, such as class="intro-text left-align". In this case, the above selector won't match the element because it expects intro to be the starting portion of the attribute value.

To ensure matching even when the class attribute contains multiple values, add a space in the attribute selector to match any element that has a class starting with the specific string. The following CSS rule demonstrates how to do this:

css
[class^="intro"], [class*=" intro"] {
    /* CSS styles */
}

Here, the first selector [class^="intro"] matches elements where intro is the first class name (e.g., class="intro-text"). The second selector [class*=" intro"] (note the space before intro in the class value) matches elements where the class attribute contains a value starting with a space followed by intro (e.g., class="someclass intro-text").

This method ensures that any element where intro appears as a standalone word beginning with intro in the class attribute value will be selected and styled.

For example, if you want to apply a specific background color and font style to all elements whose class names start with intro, you can write:

css
[class^="intro"], [class*=" intro"] {
    background-color: #f0f0f0;
    font-style: italic;
}

This CSS will select all elements whose class names start with intro and apply a light gray background and italic font.

You can easily add multiple classes to a div... For example:

html
<div class="myclass myclass-one"></div>
<div class="myclass myclass-two"></div>
<div class="myclass myclass-three"></div>

Then, in CSS, you can use the shared class to apply the same styles:

css
.myclass {...}

You can still use other classes like this:

css
.myclass-three {...}

Or if you want to be more specific in CSS, as shown below:

css
.myclass.myclass-three {...}

This isn't the direct answer to the question, but I recommend that in most cases, you simply assign multiple classes to each element:

html
<div class="myclass one"></div>
<div class="myclass two"></div>
<div class="myclass three"></div>

By doing this, you can set rules for all elements with the myclass class, and then set more specific rules for one, two, and three.

css
.myclass { color: #f00; }

.two { font-weight: bold; }

etc.

Here's a solution that should work:

shell
div[class^='myclass'], div[class*='myclass']{
    color: #F00;
}
