Utilizing a petite background image with CSS properties

Currently faced with the following issue:

I am attempting to add an image to my webpage, but it must be centered and not draggable. When I click on it, I do not want it to move. To achieve this, I have created a div:

<div id="products_logo"></div>

Along with a corresponding css file:

.products #products_logo{
    background: url('../img/shop.png') no-repeat center center;
}

As a result, two images of a shopping cart are being displayed - one in its original position (drag-able) and another at the center (not drag-able). Also, while we're here, is it more appropriate to use a div as an ID or a class? Could someone direct me to a page that explains the differences?

Thank you!

Here is some additional HTML code as requested:

<div class="products">
      <div id="products_logo"></div>
        <h1>Our Products</h1>
        <div class="products_table">
            <table>
                <tr>
                    <td id="ti1">item1</td>
                    <td id="ti2">item2</td>
                    <td id="ti3">item3</td>
                  </tr>
                  <tr>
                    <td id="ti4">item4</td>
                    <td id="ti5">item5</td>
                    <td id="ti6">item6</td>
                  </tr>
            </table>
        <div>
    </div>

Apologies for the formatting errors with the code tags.

Answer №1

When it comes to using ids and classes in HTML, there are no set rules that dictate when and where they should be applied. It's essential to understand that classes can be used multiple times while ids should only be assigned once.

<div> elements are typically utilized for creating organized layouts, with ids serving as unique identifiers for different sections within the layout.

<div id="container">
    <div id="top-section">
    </div>
    <div id="main-content">

    </div>
    <div id="bottom-section">
    </div>
</div>

In CSS, you can style ids like this:

#container {
    width: 800px;
    height: 600px;
}

Classes, on the other hand, are useful for applying consistent styles to multiple elements throughout a webpage.

<ul id="primary_nav" class="navigation">
    <li>Primary navigation links here...</li>
</ul>

<ul id="secondary_nav" class="navigation">
    <li>Secondary navigation links here...</li>
</ul>

Answer №2

An identification for a div tag is known as a div with an ID. This ID is necessary if you want to reference that specific div. A class, on the other hand, provides CSS styles to the div.

Below is a guide on how to insert a non-draggable image and eliminate unnecessary properties:

<div class="header_pic" style="border: 0px solid green">

</div>

.header_pic { background-image:url('/images/home/main_img.png'); background-repeat: no-repeat; background-position: bottom left; margin:0px; padding:0px; width:965px; height:325px; position:relative; display: inline-block; float:left; z-index:1;
}
