Cannot remove white space below footer - css

Question

I have a big bar of white space below my footer and cant figure out how to remove it. Basically I want everything below the footer to be gone.
Any help appreciated, just learning code so new to this.

function active() {
var search_bar = document.getElementById('search_bar');
if (search_bar.value == 'Search') {
search_bar.value = '';
search_bar.placeholder = 'Search';
}
}
function inactive() {
var search_bar = document.getElementById('search_bar');
if (search_bar.value == '') {
search_bar.value = 'Search';
search_bar.placeholder = '';
}
}

Answer 1

Firt of all, edit this .footer-notes css and remove left:100px; from it. It is making your page width greater then 100%
.footer_notes{
position: relative;
text-align: center;
bottom: 10px;
padding-left: 100px;
overflow: hidden;
max-width:100%;
}
then dont declare height on .third-bar this makes your footer come up even if their is content above the footer
.third_bar{
background:#000000;
position: relative;
}
Even after doing this your footer will have maybe 20px or so space below it because their is not enough content above it. If you want your footer to always stay at bottom in any device then add this to your footer's css.
.footer{
position:fixed;
background: #000000;
color: #ffffff;
bottom:0px;
width:100%;
}
If you go through with all three changes this is what your page will look like :
function active(){
var search_bar= document.getElementById('search_bar');
if(search_bar.value == 'Search'){
search_bar.value=''
search_bar.placeholder= 'Search'
}
}
function inactive(){
var search_bar= document.getElementById('search_bar');
if(search_bar.value == ''){
search_bar.value='Search'
search_bar.placeholder= ''
}
}
