html - Can I use CSS to add a bullet point to any element?

Question

Pretty simple question, but I am not sure if it is possible. I want to add an image to act as a bullet in all <h1> elements. I know I can achieve this by:

<span class='bullet'></span><h1>My H1 text here</h1>

with css:

.bullet{
    background: url('bullet.png') no-repeat;
    display:inline-block;
    vertical-align: middle;
    background-size:100%;
    height:25px;
    width:25px;
    margin-right: 5px;
}

but is there an automatic way to do the same thing? I was thinking something like:

h1{
    list-style-image: url('bullet.png');
}

but that only seems to work with <ul> elements. I really don't want to have to paste the <span> element everywhere before the <h1> element. Any ideas?

Answer 1

While you can use a :before pseudo-selector to add a "-" or "?" character in front of your element, it doesn't really make your element behave like a bullet point. Your element may look like a bullet point, but that's just a dirty hack, really, and should be avoided!

To make your element both (1) look like a bullet point and (2) behave like a bullet point, you should set the display, list-style-type and list-style-position attributes of that element.

EXAMPLE CODE

h1 {
    display: list-item;          /* This has to be "list-item"                                               */
    list-style-type: disc;       /* See https://developer.mozilla.org/en-US/docs/Web/CSS/list-style-type     */
    list-style-position: inside; /* See https://developer.mozilla.org/en-US/docs/Web/CSS/list-style-position */
}

<h1>My H1 text here</h1>
