This ensures that bots are unable to scrape your email address, whilst keeping it visible to legitimate visitors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I have combined several methods from an article at <a href=\"https:\/\/www.labnol.org\/internet\/hide-email-address-web-pages\/28364\" target=\"_blank\" rel=\"noreferrer noopener\">Labnol<\/a> to give a simple two-step solution which even beginners with WordPress should have no trouble implementing. The same code can also be used on other websites publishing systems, but the steps might vary slightly.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" style=\"padding-top:0\">\n<h2 class=\"wp-block-heading\">HTML code to create the email address<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Create a &#8220;Custom HTML&#8221; block with the following content.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;p&gt;\n    &lt;a href = \"mailto:johnATgmailDOTcom\"\n        onclick = \"this.href=this.href\n            .replace(\/AT\/,'@')\n            .replace(\/DOT\/,'.')\"&gt;\n        &lt;my-email data-user=\"john\" data-domain=\"gmail.com\"&gt;&lt;\/my-email&gt;\n    &lt;\/a&gt;\n&lt;\/p&gt;<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This block of code works like this:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>It defines a paragraph using the &lt;p&gt; and &lt;\/p&gt; tags.<\/li>\n\n\n\n<li>In  a similar way, it then defines the  email link (anchor) using &lt;a&gt; and &lt;\/a&gt; tags.\n<ul class=\"wp-block-list\">\n<li>The &#8220;href&#8221; defines what happens when you click on the link.<\/li>\n\n\n\n<li>You see here the obfuscated email address.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>When clicking the link (onclick), Javascript replaces the AT and DOT by &#8216;@&#8217; and &#8216;.&#8217;.  Your email program now receives the correct email address.<\/li>\n\n\n\n<li>The &lt;my-email&gt; tag is used to create the actual text you see on the website. The CSS code below handles the rendering.<\/li>\n<\/ol>\n\n\n\n<p class=\"has-nv-light-bg-background-color has-background wp-block-paragraph\"><em><strong>Note:<\/strong> The email address won&#8217;t be visible until the CSS code below is added to your website.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Customise the code to match the email address you are wanting to hide.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" style=\"padding-top:0\">\n<h2 class=\"wp-block-heading\">CSS code to display the email address<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Go to the &#8220;Additional CSS&#8221; panel of your theme.<br>(WordPress Dashboard -&gt; Appearance -&gt; Customise -&gt; Additional CSS)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Add the following code; modifying it to match the email address you are wanting to hide.<\/p>\n\n\n\n<pre class=\"wp-block-code has-nv-light-bg-background-color has-background\"><code> my-email::after {\n    content: attr(data-domain);\n  }\n  my-email::before {\n    content: attr(data-user) \"\\0040\";\n  }<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">You will recognise the&nbsp;my-email&nbsp;tag from the code above. This code essentially says \u201cshow the text defined by \u2018data-domain\u2019 and \u2018data-user\u2019\u201d.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The second part, with&nbsp;data-user, also includes the instruction to display an \u2018@\u2019 symbol using the ASCII reference number&nbsp;0040.<\/p>\n<\/div>\n\n\n\n<p class=\"has-text-color has-link-color wp-elements-1 wp-block-paragraph\" style=\"color:#848484;font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.085), 15px);\"><em>Code source:&nbsp;<a href=\"https:\/\/www.labnol.org\/internet\/hide-email-address-web-pages\/28364\">h<\/a><a href=\"https:\/\/www.labnol.org\/internet\/hide-email-address-web-pages\/28364\" target=\"_blank\" rel=\"noreferrer noopener\">ttps:\/\/www.labnol.org\/internet\/hide-email-address-web-pages\/28364<\/a><\/em><\/p>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">Troubleshooting<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">These steps are fairly simple to undertake.
