+# Escaping Smarty parsing
+
+It is sometimes desirable or even necessary to have Smarty ignore
+sections it would otherwise parse. A classic example is embedding
+Javascript or CSS code in a template. The problem arises as those
+languages use the { and } characters which are also the default
+[delimiters](../language-builtin-functions/language-function-ldelim.md) for Smarty.
+
+> **Note**
+>
+> A good practice for avoiding escapement altogether is by separating
+> your Javascript/CSS into their own files and use standard HTML methods
+> to access them. This will also take advantage of browser script
+> caching. When you need to embed Smarty variables/functions into your
+> Javascript/CSS, then the following applies.
+
+In Smarty templates, the { and } braces will be ignored so long as they
+are surrounded by white space. This behavior can be disabled by setting
+the Smarty class variable [`$auto_literal`](../../programmers/api-variables/variable-auto-literal.md) to
+false.
+
+## Examples
+
+```smarty
+<script>
+   // the following braces are ignored by Smarty
+   // since they are surrounded by whitespace
+   function foobar {
+    alert('foobar!');
+   }
+   // this one will need literal escapement
+   {literal}
+    function bazzy {alert('foobar!');}
+   {/literal}
+</script>
+```  
+     
+[`{literal}..{/literal}`](../language-builtin-functions/language-function-literal.md) blocks are used
+for escaping blocks of template logic. You can also escape the braces
+individually with
+[`{ldelim}`, `{rdelim}`](../language-builtin-functions/language-function-ldelim.md) tags or
+[`{$smarty.ldelim}`,`{$smarty.rdelim}`](../language-variables/language-variables-smarty.md#smartyldelim-smartyrdelim-languagevariablessmartyldelim)
+variables.
+
+Smarty's default delimiters { and } cleanly represent presentational
+content. However, if another set of delimiters suit your needs better,
+you can change them with Smarty's
+[`$left_delimiter`](../../programmers/api-variables/variable-left-delimiter.md) and
+[`$right_delimiter`](../../programmers/api-variables/variable-right-delimiter.md) values.
+
+> **Note**
+>
+> Changing delimiters affects ALL template syntax and escapement. Be
+> sure to clear out cache and compiled files if you decide to change
+> them.
+
+```php
+<?php
+
+$smarty->left_delimiter = '<!--{';
+$smarty->right_delimiter = '}-->';
+
+$smarty->assign('foo', 'bar');
+$smarty->assign('name', 'Albert');
+$smarty->display('example.tpl');
+```
+
+Where the template is:
+
+```smarty
+Welcome <!--{$name}--> to Smarty
+<script language="javascript">
+  var foo = <!--{$foo}-->;
+  function dosomething() {
+    alert("foo is " + foo);
+  }
+  dosomething();
+</script>
+```
