1. Edit your theme's existing app/navbar/navbar.component.html file. This file defines the entire <nav> which displays the navigation header across the entire DSpace site.  While much of the content in this <nav> is loaded dynamically via other Angular components, it is possible to easily add a hardcoded link to the existing header.  Find the section of this <nav> which is the <div idrole="collapsingNavmenubar">, as that's where you'll want to add your new link.  See inline comments in the example below.

   Code Block
   title navbar.component.html
   <nav> ... <!-- This DIV is where theThe header links are added dynamically. You should see it surrounding all linksembedded inunder the header if you view HTML source role="menubar" div tag --> <div idrole="collapsingNav" ... > <!-- The links themselves are in an unordered list (UL) --> <ulmenubar" class="navbar-nav" ... >   ... <!-- Add your new link at the end (or beginning) of this DIV ULtag in a new LIDIV tag --> <!-- NOTE: All classes used below are the same Bootstrap CSS classes used by our 'dspace' and 'custom' themes. You can modify them if the link doesn't look correct in your theme. -->       <li class="nav-item d-flex align-items-center"> 't look correct in your theme. --> <div class="ds-menu-item-wrapper text-md-center"> <a<a role="menuitem" href="http://dspace.org" class="navds-menu-linkitem">DSpace.org</a> </div> </li> </ul> </div> </nav>

   
   

2. Obviously, you can also make additional modifications to the HTML of the header in this file, as necessary for your navigation header.  Keep in mind though that anything you remove may impact the dynamic content that is pulled into this navigation header. 
   1. An example is that the header logo for the "dspace" theme also exists in this same file. 
3. Any changes require rebuilding your UI. If you are running in "dev mode" (npm run start:dev), then the UI will restart automatically whenever changes are detected.

1. First, you'll want to decide if you want to modify just the footer's HTML, or the footer's styles (CSS/Sass), or both. 
   1. If you want to modify the HTML, you'll need to create a copy of "footer.component.html" in your theme, where you place your changes.
   2. If you want to modify the styles, you'll need to create a copy of "footer.component.scss" in your theme, where you place your changes.

2. Edit your theme's app/footer/footer.component.ts file. Swap the "templateUrl" and "styleUrls" properties, based on which you want to modify in your theme. 

   Code Block
   title footer.component.ts
   @Component({ selector: 'ds-footer',  // If you want to modify styles, then... // Uncomment the styleUrls which references the "footer.component.scss" file in your theme's directory // and comment out the one that references the default "src/app/footer/footer.component.scss" styleUrls: ['footer.component.scss'], //styleUrls: ['../../../../app/footer/footer.component.scss'], // If you want to modify HTML, then...  // Uncomment the templateUrl which references the "footer.component.html" file in your theme's directory // and comment out the one that references the default "src/app/footer/footer.component.html" templateUrl: 'footer.component.html' //templateUrl: '../../../../app/footer/footer.component.html' })

   
   

3. Now, based on what you want to modify, you will need to either update your theme's copy of footer.component.html or footer.component.scss or both.
   1. To change footer HTML: Your theme's version of the footer.component.html file will be empty by default. Copy over the default HTML code from src/app/footer/footer.component.html into your version of this file.
   2. To change footer Styles: Your theme's version of the footer.component.scss file will be empty by default. Copy over the default Sass code from src/app/footer/footer.component.scss into your version of this file.
4. Modify the HTML or Sass as you see fit.
   1. If you want to add images, add them to your theme's assets/images folder.  Then reference them at the /assets/[theme-name]/images/ URL path.
   2. Keep in mind, all Bootstrap variables, utility classes & styles can be used in these files. Take advantage of Bootstrap when you can do so.

5. DSpace also has a option to display a two-level footer, which is becoming more common these days.  By default. DSpace just displays a small, bottom footer.  But, you can enable a top footer (above that default footer) by add this line into your theme's footer.component.ts

   Code Block
   title footer.component.ts
   export class FooterComponent extends BaseComponent { // This line will enable the top footer in your theme   showTopFooter = true; }

   This top footer appears in the footer.component.html within a div.  Notice the "*ngIf='showTopFooter'@if(showTopFooter)", which only shows that div when that variable is set to "true"

   Code Block
   title footer.component.html
   <footer class="text-lg-start">   <!-- This div and everything within it only displays if showTopFooter=true --> <div *ngIf="showTopFooter"@if (showTopFooter) { <div class="top-footer"> ... </div> }   <!-- The bottom footer always displays --> <div class="bottom-footer ..."> ... </div> </footer>
