Modern AdSense ads are responsive and Google designs them, so you should paste the ad code as it is. You can still style the space around an ad with your own CSS, as long as the ad itself is not altered or disguised.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_89 counter-hierarchy ez-toc-counter ez-toc-custom ez-toc-container-direction\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<label for=\"ez-toc-cssicon-toggle-item-6af83cc84b86d\" class=\"ez-toc-cssicon-toggle-label\"><span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #1a202c;color:#1a202c\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #1a202c;color:#1a202c\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-6af83cc84b86d\" checked aria-label=\"Toggle\" \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2007\/06\/google-adsense-ad-border-with-rounded-corners\/#How_AdSense_rounded_corners_worked_in_2007\" >How AdSense rounded corners worked in 2007<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2007\/06\/google-adsense-ad-border-with-rounded-corners\/#AdSense_rounded_corners_and_ad_borders_in_2026\" >AdSense rounded corners and ad borders in 2026<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2007\/06\/google-adsense-ad-border-with-rounded-corners\/#Related_AdSense_guides\" >Related AdSense guides<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2007\/06\/google-adsense-ad-border-with-rounded-corners\/#FAQ\" >FAQ<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2007\/06\/google-adsense-ad-border-with-rounded-corners\/#Can_I_still_get_rounded_corners_on_AdSense_ads\" >Can I still get rounded corners on AdSense ads?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2007\/06\/google-adsense-ad-border-with-rounded-corners\/#Is_it_allowed_to_add_CSS_around_AdSense_ads\" >Is it allowed to add CSS around AdSense ads?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2007\/06\/google-adsense-ad-border-with-rounded-corners\/#What_does_google_ui_features_rc_10_mean\" >What does google_ui_features rc:10 mean?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2007\/06\/google-adsense-ad-border-with-rounded-corners\/#Did_rounded_corners_increase_AdSense_clicks\" >Did rounded corners increase AdSense clicks?<\/a><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"How_AdSense_rounded_corners_worked_in_2007\"><\/span>How AdSense rounded corners worked in 2007<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Back then, most publishers matched the ad border color to their page background to make the border disappear, because square-edged borders clashed with many designs. In June 2007 a new <strong>Corner Styles<\/strong> option appeared in the AdSense ad setup with three choices:<\/p>\n<ul>\n<li><em>Square corners<\/em> (the default)<\/li>\n<li><em>Slightly rounded corners<\/em><\/li>\n<li><em>Very rounded corners<\/em><\/li>\n<\/ul>\n<p>Choosing a style added one extra line to the generated ad code:<\/p>\n<pre><code>google_ui_features = \"rc:10\"; \/\/ very rounded corners\ngoogle_ui_features = \"rc:6\";  \/\/ slightly rounded corners\ngoogle_ui_features = \"rc:0\";  \/\/ square corners<\/code><\/pre>\n<p>This only worked with the old JavaScript ad code that used variables like <code>google_ad_width<\/code> and <code>google_color_border<\/code>. That code style has long been replaced by the current asynchronous ad tag, so adding these lines to a modern ad unit does nothing useful.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"AdSense_rounded_corners_and_ad_borders_in_2026\"><\/span>AdSense rounded corners and ad borders in 2026<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Today&#8217;s AdSense is built around responsive display ads and <a href=\"https:\/\/adsense.google.com\/\" target=\"_blank\" rel=\"noopener\">Auto ads<\/a>.
