As discussed in the SharePoint: Hide View All Site Content and Recycle Bin Post. The same instructions can be adapted to hide other unwanted SharePoint content.
Below is a selection of CSS code that can be used to “rebrand” SharePoint using a Content Editor Web Part:
<style>
/* breadcrumbs */
.ms-titlearea {
display: none;
}
/* Tabs */
.ms-banner {
display: none;
}
/* Title Bar */
.ms-pagetitle {
display: none;
}
/* Search function */
.ms-searchform {
display: none
}
/* Welcome and help stuff */
.ms-globallinks {
display: none
}
/* Remove shadings from right */
.ms-sitetitle {
background-color: white
}
</style>
