"I've made my portfolio with HTML and CSS, so when I check it on my phone, it zooms out first. I need you to correct this."

Sure, it sounds like you need to make your website responsive so it displays correctly on different screen sizes. Here's how you can do it:

1. Use a Viewport Meta Tag: This tag gives the browser instructions on how to control the page's dimensions and scaling. Add the following line of code in the head of your HTML file:

<meta name="viewport" content="width=device-width, initial-scale=1">

2. Use Media Queries: Media queries are useful for applying different CSS styles to different devices based on their characteristics, especially their width and height. You can add it in your CSS file like this:

@media screen and (max-width: 600px) {
  body {
    background-color: lightblue;
  }
}

In this example, if the browser window is 600px or smaller, the background color will be lightblue.

3. Use Responsive Images: If your portfolio includes images, make sure they are also responsive. You can make an image responsive by adding the following CSS:

img {
  max-width: 100%;
  height: auto;
}

This will make sure your images are not larger than their container and they will scale nicely on any device.

4. Use Responsive Units: Instead of using pixels which are absolute, use relative units like percentages, ems or rems for sizing elements. This will help elements scale relative to each other and maintain their proportions on different screen sizes.

Remember to test your website on different devices or use the device toolbar in Chrome's developer tools to simulate different screen sizes and make sure everything looks as expected.
