Why Margin-Top Works with Inline-Block but Not with Inline
In web development, understanding the difference between inline and inline-block is crucial for shaping elements' behavior on a page. This question attempts to clarify the discrepancy in top margin application between these two display properties.
Inline and Inline-Block
The CSS2 specification defines inline as a value that represents inline elements. Such elements appear as one continuous line without interruptions. Inline-block, on the other hand, creates inline-level block containers, meaning these elements behave like blocks within inline formatting. As illustrated in the CSS2 documentation:
- Inline: "This value causes an element to generate one or more inline boxes."
- Inline-block: "This value causes an element to generate an inline-level block container. The inside of an inline-block is formatted as a block box, and the element itself is formatted as an atomic inline-level box."
Margin Respect
Furthermore, the CSS2 specification outlines the margin respect of inline elements:
"In an inline formatting context, boxes are laid out horizontally, one after the other, beginning at the top of a containing block. Horizontal margins, borders, and padding are respected between these boxes."
This distinction explains why margin-top does not work with inline elements. Inline elements are restricted to respecting only horizontal margins, while block-level elements like inline-blocks respect both horizontal and vertical margins.
Example
Consider the HTML and CSS provided in the question:
<!DOCTYPE html> <head> <link rel="stylesheet" type="text/css" href="MyFirstWebsite.css"> <title>Max Pleaner's First Website</title> </head> <body> <h1>Welcome to my site.</h1> </body> </html>
body {
background-image: url('sharks.jpg');
}
h1 {
background-color: #1C0245;
display: inline;
padding: 6.5px 7.6px;
margin-left: 100px;
margin-top: 25px;
}In this case, the h1 element will only display a horizontal margin of 100px when the display property is set to inline. However, if the display property is changed to inline-block, the margin-top of 25px will be applied, as the h1 element is then treated as a block-level element within the inline context.
