If you’ve linked a CSS file to your HTML but the changes aren’t appearing on your website, there are several common reasons this might occur. First, verify that the path specified in the href
attribute of the link tag in your HTML is correct, as an incorrect or misspelled path will prevent the CSS file from loading. Next, check that the CSS syntax in your file is accurate and free of errors, since even a minor mistake can cause the entire stylesheet to fail. Additionally, ensure the link to the CSS file is placed before the closing </head>
tag in your HTML; if it’s positioned after the body tag, the CSS may not load correctly. You should also consider that your browser might be caching an older version of your CSS file, which can block your updates from showing, so try clearing your browser cache and reloading the page. Finally, if your CSS selectors lack specificity, they might be overridden by other styles, either from your own CSS or from external stylesheets, so consider using more specific selectors or the !important
declaration to increase the priority of your styles.
