Pernahkah Anda menulis kode dengan menggunakan tag <PRE> di blogspot. Jika belum, mungkin ini saatnya. Mengapa tag <PRE>? bukankah lebih baik menggunakan
syntax highlighter?
Tag <PRE> dalam kode HTML digunakan khusus untuk menuliskan kode. Dengan menggunakan tag <PRE> maka sebuah postingan akan memelihara indent dari kode tersebut, ini sangatlah penting.
Penggunaan tag <PRE>:
<PRE> code HTML, VB, C++, CSS, dll </PRE>
Contoh kode CSS yang menggunakan tag <pre>:
<b:includable id='feedLinks'>
<b:if cond='data:blog.pageType != "item"'> <!-- Blog feed links -->
<b:if cond='data:feedLinks'>
<div class='blog-feeds'>
<b:include data='feedLinks' name='feedLinksBody'/>
</div>
</b:if>
<b:else/> <!--Post feed links -->
<div class='post-feeds'>
<b:loop values='data:posts' var='post'>
<b:if cond='data:post.allowComments'>
<b:if cond='data:post.feedLinks'>
<b:include data='post.feedLinks' name='feedLinksBody'/>
</b:if>
</b:if>
</b:loop>
</div>
</b:if>
</b:includable>
Bandingkan dengan kode di bawah:<b:includable id='feedLinks'>
<b:if cond='data:blog.pageType != "item"'> <!-- Blog feed links -->
<b:if cond='data:feedLinks'>
<div class='blog-feeds'>
<b:include data='feedLinks' name='feedLinksBody'/>
</div>
</b:if>
<b:else/> <!--Post feed links -->
<div class='post-feeds'>
<b:loop values='data:posts' var='post'>
<b:if cond='data:post.allowComments'>
<b:if cond='data:post.feedLinks'>
<b:include data='post.feedLinks' name='feedLinksBody'/>
</b:if>
</b:if>
</b:loop>
</div>
</b:if>
</b:includable>
Kode VB6.0 di bawah ini menggunakan tag <PRE>:
