## Call it > Brainpower mode ### Context Congrats! You created the very first base for your entity and you witnessed its appearance in the Digital World - your browser.. However, it is still a tiny seed of the marvelous thing it could become. Be patient; there's still a bit of work to do. ### Directions First of all, instead of writing down what things are _(you're not writing down on your hand the word 'hand', are you?)_, we're going to identify them semantically with the very practical [id attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/id). This `id` has to be a **unique** identifier on your webpage, allowing you to target your element when needed. You can compare it to your name and surname; this is what identifies you to other people, and if someone's calling you by your name, you answer. ### Instructions So let's identify the 3 elements we have so far: in each section, remove the text content from inside the tag and set it as the value of the `id` attribute of the corresponding `section` text. **Run your code in the editor preview:** \ you don't see _anything_? Don't freak out! \ Inspect the HTML that has been created with your [browser inspector tool](https://developer.mozilla.org/en-US/docs/Learn/Common_questions/What_are_browser_developer_tools), and if you done it correctly, you should see the 3 sections inside the `body` with the `id` attribute set in your HTML structure. ### Code examples To set the `id` of a `div` tag to `"my-lil-div"`: ```html
