hi
you have to change your style.css of the theme
bootstrap works with two types of container
1) container-fluid: it will use the full width of your device
look into your theme and change
div class="container"
into
div class="container-fluid"
2) container: a responsive area with a width depending on device
if yor device has min 1200 px then width of container is 1170px
if yor device has min 992 px then width of container is 970px
and so on
if you want to fix it to your witdh you have to add following lines to your css or your theme:
.container {
width: 1000px !important;
}
(to have always 1000px, even if device is smaller) or
.container {
max-width: 1000px !important;
}
to keep it responsive to max 1000px
