CSS positioning alignment

Could someone please explain to me why changing the position to relative causes the "facebook and Facebook helps you connect and share with the people in your life" text to display at the top of the page? I've only been studying CSS for three days. Thanks in advance!

Here is the HTML code snippet:

<!DOCTYPE html>
<html>
 
<head>
<link rel="stylesheet" href="henry.css">
</head>
 
<body>
    <div class="h1">
        <h1 class="h">facebook</h1>
        <p class="pr">Facebook helps you connect and share with the people in your life.</p>
        </div>
</body>
 
</html>

CSS code snippet:

.h1{
    position: absolute;
    left: 10%;
    top: 40%;
    width: 550px;
}

Answer №1

If you're looking to align elements, consider starting with flexbox (remember to add flex to the parent elements you want to align): https://css-tricks.com/snippets/css/a-guide-to-flexbox/

If you encounter difficulties with flexbox, you can also try aligning with grid: https://www.w3schools.com/css/css_grid.asp


FLEXBOX VS GRID:

Flexbox: allows for one-directional alignment, useful for centering elements vertically in a list of posts

Grid: enables bidirectional alignment, commonly used for structuring page layouts with sections such as "header, footer, menu, body..." You can also utilize flexbox within a grid, especially in the footer section

(It may seem complex at first, but it will eventually make sense to you :D)


These properties (flexbox, grid, etc.) create a flexible structure where one HTML element can influence or support another. Experiment with the "inspect element" feature in your browser to see how elements interact on the screen when you remove HTML nodes like DIVs, SPANs, etc.

Try adding a div element with position absolute within these structures. Then, use the inspect element tool to delete this added element and observe how the positioning of elements shifts to accommodate the absence of this element.

Answer №2

position:absolute places an element in relation to its first non-static ancestor element. In this scenario, the div with the class name "h1", which encloses those two sentences, has the <body> element as its ancestor: this causes your div to be positioned at the top.

Quick tip: try to avoid using keywords as class names, as it can lead to confusion. I would suggest switching from to

Answer №3

position: relative behaves differently compared to absolutely positioned elements when it comes to alignment using top, bottom, left, or right. Instead of adjusting their position in relation to the viewport, these properties shift their position based on other elements in the DOM.
In this scenario where there are no other elements, the element will end up at the top of the page.


position: absolute, on the other hand, disregards all other elements in the layout.

If you wish to give the div an offset, you can utilize the margin CSS property.
(margin-top, margin-left, margin-bottom, margin-right).
However, adding a top offset to a relatively positioned element requires changing its display property, like using display: flex or display: grid.
Apologies for the brief initial response, I hope this explanation clarifies things for you.
