Introduction and Concept of Basic Block and Inline Elements in CSS
When working with CSS and HTML, how to display elements on a page is one of the key concepts. In CSS, there are two main models for displaying elements: block element and inline element. Each of these models plays an important role in the presentation or structuring of the page.
Block elements generally take up the entire width of the page, starting on a new line, as seen in <div>, <h1> through <h6>, and <p>. These elements can fully occupy their own horizontal space and always start on a new line.
On the other hand, inline elements are typically smaller and related to tags like <span>, <a>, and <img>. These elements only take up as much space as their content and can exist in the same line as other elements.
Understanding the differences and applications of each of these two models allows you to create cleaner and more organized code in larger projects. Choosing correctly between block and inline can greatly affect the user experience and layout appearance.
Code Example and Differences

</head>
<body>
<div>

Code Description
<div>...</div> is a block element that fills the entire width available.<span>...</span> is an inline element that only takes up as much space as its content, in this example containing a single text segment that remains in the same line as other remaining elements.style contains CSS settings for styling block and inline elements, displaying the differences well between them.div in CSS, using border and margin creates gaps around itself to provide more visible separation from the surrounding elements.span only changes the text color and stays in line with other remaining elements that may be arranged in this manner.
