br / HTML

Question

Hello I do not understand this <td><br /></td> How can explain what it does and what happens if we skip br /? I cannot find the difference and meaning

Answer 1

<br /> is just a new line (an enter, to be clear), so you won’t be able to see anything inside the table cell, anyway with <td></td> your table cell would disappear, depending on the browser, unless you specify via css its behaviour:

table {
empty-cells: show;
}
