Simple Pre Code with Selection

For friends who often share blogger tutorials would have been familiar with the application of code either HTML, CSS, JavaScript or jQuery in the post. And as a place to apply the codes in the post, you need to wrap each code with a pre tag.

Examples of HTML code declarations wrapped with pre tags

<pre><code><button>Press Me!</button></code></pre>

The above examples are previously pre-parsed HTML code and a simple example of implementing pre tags. The appearance of the pre tag can actually be developed to look different from the usual. As in posts I've ever shared by adding a plug in / script Prism Syntax Highlighter in Blogger.

Well here I will try to share the concept of pre tag is more simple without the need for an external script that can apply to the blog. 

Ok go ahead please follow these simple steps: 

Go to Blogger> Template> Click Edit HTML> Save the CSS code below before  ]]></b:skin>or</style>

/* CSS Simple Pre Code */
pre {
    background: #fff;
    white-space: pre;
    word-wrap: break-word;
    overflow: auto;
}

pre.code {
    margin: 20px 25px;
    border: 1px solid #d9d9d9;
    border-radius: 2px;
    position: relative;
    box-shadow: 0 1px 1px rgba(0,0,0,.08);
}

pre.code label {
    font-family: sans-serif;
    font-weight: normal;
    font-size: 13px;
    color: #444;
    position: absolute;
    left: 1px;
    top: 16px;
    text-align: center;
    width: 60px;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    pointer-events: none;
}

pre.code code {
    font-family: "Inconsolata","Monaco","Consolas","Andale Mono","Bitstream Vera Sans Mono","Courier New",Courier,monospace;
    display: block;
    margin: 0 0 0 60px;
    padding: 15px 16px 14px;
    border-left: 1px solid #d9d9d9;
    overflow-x: auto;
    font-size: 13px;
    line-height: 19px;
    color: #444;
}

pre::after {
    content: "double click to selection";
    padding: 0;
    width: auto;
    height: auto;
    position: absolute;
    right: 18px;
    top: 14px;
    font-size: 12px;
    color: #aaa;
    line-height: 20px;
    overflow: hidden;
    -webkit-backface-visibility: hidden;
    transition: all 0.3s ease;
}

pre:hover::after {
    opacity: 0;
    visibility: visible;
}

pre.code-css code {
    color: #0288d1;
}

pre.code-html code {
    color: #558b2f;
}

pre.code-javascript code {
    color: #f57c00;
}

pre.code-jquery code {
    color: #78909c;
}

Next save the script below before the closing tag </body>

<script type='text/javascript'>
//<![CDATA[
//Pre Auto Selection
$('i[rel="pre"]').replaceWith(function() {
    return $('<pre><code>' + $(this).html() + '</code></pre>');
});
var pres = document.querySelectorAll('pre,kbd,blockquote');
for (var i = 0; i < pres.length; i++) {
  pres[i].addEventListener("dblclick", function () {
    var selection = getSelection();
    var range = document.createRange();
    range.selectNodeContents(this);
    selection.removeAllRanges();
    selection.addRange(range);
  }, false);
}
//]]>
</script>

The script above serves to automatically select each buddy to double-click on areas wrapped in pre, kbd, and blockquote tags. 

After that save the template. 

For application on post, please add the code below in HTML post tab

<pre class='code code-html'><label>HTML</label><code>... code HTML (yang telah diparse) di sini ...</code></pre>

<pre class='code code-css'><label>CSS</label><code>... code CSS di sini ...</code></pre>

<pre class='code code-javascript'><label>JS</label><code>... code JavaScript di sini ...</code></pre>

<pre class='code code-jquery'><label>Jquery</label><code>... code jQuery di sini ...</code></pre>

RESULT

If you want a pre tag display with dark colors, please use this code
