div.center {
width: 70%;
margin: 0 auto;
}To center a div (with margin), you need to assign an “Auto” margin both from the left and right sides.
Since the <div> is a block-level element in HTML, you don’t need to write display: block; in your CSS again. Because it’s already a block-level element by born.
In this example- I give it (div) a 70% width for better visualization of centering the div. But you don’t need to give it a width value to center align a div.

</div> 1 common issue fixed for centering a div with CSS absolute positioning
In the above example, I used width: 700px; for the child <div> (.center).
But if you use a relative length instead of an absolute length, the <div> will become smaller based on the top & left distance. Let me clarify more.
If you use max-width instead of width, then your <div> will become smaller by the absolute positioning and depending on the top & left distance.
Because the <div> is a block-level element in HTML. So it will not only start with a new line but also shrink horizontally to display its whole content (just like a paragraph behaves).
If you need to use the max-width anyhow, then there is a fix for this issue. After you assign the max-width, also you have to write anyone of the following CSS properties:
width: fit-content; or width: max-content;
div.center {
max-width: 700px;
width: fit-content; /*this property will solve the issue*/
/*or*/
/*width: max-content;*/
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
