what is <span> ??? and what is colspan ??

Question

I want to know it

Answer 1

span is an element and colspan is an attribute..
span example:
<h1>Hello this is example of <span> span element </span>
now in above example, u see that span is inserted within h1 tag.. span is an inline element.. now I can add separate styling to span element it is similar to div but it is inline element, therefore it is just a container with inline properties

and Colspan it is a table element attribute
<table> <tr>
<th>Column 1 heading</th>
<th>Column 2 heading</th>
<th>Column 3 heading</th>
</tr>
<tr>
<td>Row 2, cell 1</td>
<td colspan="2">Row 2, cell 2, also spanning Row 2, cell 3</td>
</tr>
<tr> <td rowspan="2">Row 3, cell 1, also spanning Row 4, cell 1</td>
<td>Row 3, cell 2</td>
<td>Row 3, cell 3</td>
</tr>
<tr>
<td>Row 4, cell 2</td>
<td>Row 4, cell 3</td>
</tr>
</table>

here Colspan with value two, which means that table data width will take up the two fields space in column wise..
and rowspan does the same but in row wise

Answer 2

<span> is an inline element for grouping atuff.
Colspan is an attribute for table cells, <td>, specifying how wide they are
