Good Evening,
I have a website and so far I am copying the navigation code across every page. Annoying right

However I’d like to use PHP or something to hold the HTML so I only have to edit one file. However because of the way the navigation bar operates there’s a class called which keeps the clicked link highlighted to show the user which page they are on.

Here’s the code:

<nav>
                    <ul class="menu">
                        <li class="active"><a href="index.html"><strong><strong>Home</strong></strong></a></li>
                        <li><a href="services.html"><strong><strong>services</strong></strong></a>
                          <ul>
                                <li><a herf="services.html">Repairs</a>
                                    <ul>
                                        <li><a href="phonerep.html">Phone Repairs</a>
                                      <li><a href="podrep.html">Ipod Repairs</a>
                                    <li><a href="padrep.html">Ipad Repairs</a>
                                  <li><a href="comprep.html">Computer & Laptop Repairs</a>
                                  </ul>
                                </li>
                                <li><a href="compmain.html">Maintenance & Upgrades</a>
                                    <ul>
                                        <li><a href="compmain.html">Computers & Laptops</a>
                                  </ul>
                              </li>
                              <li><a href="tuition.html">Tutoring</a></li>
                              <li><a href="spechelp.html">Specialist Help</a></li>
                          </ul>
                        </li>
                        <li><a href="iphone.html"><strong><strong>Prices</strong></strong></a>
                            <ul>
                                <li><a href="iphone.html">Iphone</a>
                                 <li><a href="ipod.html">Ipod</a>
                                  <li><a href="ipad.html">Ipad</a>
                                    <li><a href="complap.html">Computer and Laptop</a>
                          </ul>
                        <li><a href="about.html"><strong><strong>about</strong></strong></a></li>
                        <li><a href="contactus.html"><strong><strong>Contact</strong></strong></a></li>
                    </ul>
                </nav>

Thank you for your time.
