Best Practices for Mixing HTML and CSS in Full-Stack Development

1. Use Semantic HTML:
   Make sure to use HTML5 tags that describe content better, like <header>, <footer>, and <article>.
   This helps people with disabilities use your site more easily and can also make it show up more in search results.
   Sites that use these tags can boost their search visibility by 20%.

2. CSS Organization:

   • BEM Method:
     Follow a naming system called Block, Element, Modifier.
     This makes your styles clearer and easier to manage.
   • Modular CSS:
     Use CSS modules to limit the parts of the page your styles affect.
     This way, you can avoid problems when different styles fight each other.
     It can even cut down on style conflicts by 30%.

3. Responsive Design:
   Use responsive design methods, like media queries, to make sure your site looks good on all devices.
   Remember, about 50% of web traffic comes from mobile devices!

4. Performance Optimization:
   Keep your CSS small and use techniques like critical CSS.
   This can help your pages load faster, helping to speed them up by up to 45%.

Following these tips will make your website easier to maintain and better for users.
