### From a Hidden String to an Interactive UI: Rendering Your Search History In the previous task, you brilliantly gave your application a memory by implementing the `saveCityToHistory` function. You are now successfully capturing each valid search and persisting it in the browser's `localStorage`. This is a fantastic step, but right now, that memory is invisible. The user has no idea that their history is being saved. It's time to bridge the gap between the stored data and the user interface. In this task, we will read the history array from `localStorage` and dynamically generate a list of clickable buttons on the page. This will transform the invisible data into a powerful, convenient feature for your users, allowing them to see and re-access their recent searches with a single click. ### Step 1: Carving Out Space in the UI First, we need a dedicated place in our HTML to display the history buttons. A new section in our layout, perhaps alongside the main content, is a perfect spot. We'll add a container element that our JavaScript can target. Let's update your `index.html`. We'll add a new `

` element, which is a semantically correct tag for content that is tangentially related to the main content (like a search history sidebar). ```html

``` *Note: You may need to adjust your existing HTML structure slightly to fit this new sidebar layout. The key is to add the `

` and its child `

`.* ### Step 2: Styling the History Section Now, let's add some styles in `style.css` to make our new history section look clean and the buttons look interactive. ```css /* In style.css */ /* You may need a layout for the sidebar and main content */ .main-layout { display: flex; flex-wrap: wrap; /* Allows stacking on smaller screens */ gap: 2rem; } .sidebar { flex: 1; /* Takes up some space */ min-width: 250px; /* Ensures it doesn't get too squished */ } .weather-display { flex: 3; /* Takes up more space */ } /* NEW: Styles for the history section */ #history-section h2 { margin-top: 1.5rem; border-bottom: 2px solid #eee; padding-bottom: 0.5rem; } #history-container { display: flex; flex-direction: column; /* Stack buttons vertically */ gap: 0.5rem; /* Space between buttons */ margin-top: 1rem; } /* Style for each dynamically created history button */ .history-btn { width: 100%; padding: 0.75rem; font-size: 1rem; background-color: #f0f0f0; border: 1px solid #ddd; border-radius: 4px; cursor: pointer; text-align: left; transition: background-color 0.2s ease-in-out; } .history-btn:hover { background-color: #e0e0e0; } ``` ### Step 3: The `renderHistory` JavaScript Function This is where the magic happens. We will create a new function, `renderHistory`, whose sole responsibility is to draw the history buttons on the screen based on the data in `localStorage`. Here's the plan for the function: 1. Get a reference to the `#history-container` div. 2. Read and parse the history array from `localStorage`. 3. **Crucially, clear any existing buttons** from the container. This prevents duplicates from appearing every time we render. 4. Loop through the history array. For each city, create a new `
