I would like to know how to fix a table header even if we scroll down on a website and out of the table view. I would like to use css style to do this. Thank you.
I would also like to know how to fix an element on a webpage so it always appears even when we scroll down. The image can be text. Use div and css

Taken from an old post of mine, here's an example of both things that you want done together in one fiddle.
JQuery:
function moveScroll() {
var scroll = $('#table-container').offset().top;
var anchor_top = $("#maintable").offset().top;
var anchor_bottom = $("#bottom_anchor").offset().top;
if (scroll > anchor_top && scroll < anchor_bottom) {
clone_table = $("#clone");
if (clone_table.length === 0) {
clone_table = $("#maintable").clone();
clone_table.attr({
id: "clone"
}).css({
position: "fixed",
"pointer-events": "none",
left: $("#maintable").offset().left + 'px',
top: 130
}).width($("#maintable").width());
$("#table-container").append(clone_table);
$("#clone").width($("#maintable").width());
$("#clone thead").css({
visibility: "true"
});
$("#clone tbody").css({
visibility: "hidden"
});
var footEl = $("#clone tfoot");
if (footEl.length) {
footEl.css({
visibility: "hidden"
});
}
}
} else {
$("#clone").remove();
}
}
$('#table-container').scroll(moveScroll);

You would do something like this by tapping into the scroll event handler on window, and using another table with a fixed position to show the header at the top of the page.
Example:
var tableOffset = $("#table-1").offset().top;
var $header = $("#table-1 > thead").clone();
var $fixedHeader = $("#header-fixed").append($header);
$(window).bind("scroll", function() {
var offset = $(this).scrollTop();
if (offset >= tableOffset && $fixedHeader.is(":hidden")) {
$fixedHeader.show();
}
else if (offset < tableOffset) {
$fixedHeader.hide();
}
});
body { height: 1000px; }
#header-fixed {
position: fixed;
top: 0px; display:none;
background-color:white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="table-1">
<thead>
<tr>
<th>Header1</th>
<th>Header2</th>
<th>Header3</th>
</tr>
</thead>
<tbody>
<tr>
<td>info</td>
<td>info</td>
<td>info</td>
</tr>
<tr>
<td>info</td>
<td>info</td>
<td>info</td>
</tr>
<tr>
<td>info</td>
<td>info</td>
<td>info</td>
</tr>
</tbody>
</table>
<table id="header-fixed"></table>
