+## Enabling auto-escaping
+By default, Smarty does not escape anything you render in your templates. If you use
+Smarty to render a HTML-page, this means that you will have to make sure that you do
+not render any characters that have a special meaning in HTML, such as `&`, `<` and `>`,
+or apply the [escape modifier](../designers/language-modifiers/language-modifier-escape.md) 
+to anything you want to render.
+
+If you forget to do so, you may break your HTML page, or even create a vulnerability for 
+attacks known as [XSS or Cross Site Scripting](https://cheatsheetseries.owasp.org/cheatsheets/Cross_Site_Scripting_Prevention_Cheat_Sheet.html).
+
+Luckily, you can tell Smarty to automatically apply the escape modifier to any dynamic part of your template.
+It's like Smarty magically adds `|escape` to every variable you use on a web page.
+
+Enable auto-escaping for HTML as follows:
+```php
+$smarty->setEscapeHtml(true);
+```

+## Combining Modifiers

-    > **Note**
-    >
-    > Second, in Smarty 2.x, modifiers were applied to the result of
-    > math expressions like `{8+2}`, meaning that
-    > `{8+2|count_characters}` would give `2`, as 8+2=10 and 10 is two
-    > characters long. With Smarty 3, modifiers are applied to the
-    > variables or atomic expressions before executing the calculations,
-    > so since 2 is one character long, `{8+2|count_characters}`
-    > gives 9. To get the old result use parentheses like
-    > `{(8+2)|count_characters}`.
+You can apply any number of modifiers to a variable. They will be
+applied in the order they are combined, from left to right. They must be
+separated with a `|` (pipe) character.

- Custom modifiers can be registered
-    with the [`registerPlugin()`](../../programmers/api-functions/api-register-plugin.md)
-    function.
+```php
+<?php
+
+$smarty->assign('articleTitle', 'Smokers are Productive, but Death Cuts Efficiency.');
+```
+
+where template is:
+
+```smarty
+{$articleTitle}
+{$articleTitle|upper|spacify}
+{$articleTitle|lower|spacify|truncate}
+{$articleTitle|lower|truncate:30|spacify}
+{$articleTitle|lower|spacify|truncate:30:". . ."}
+```
+
+
+The above example will output:
+
+```
+Smokers are Productive, but Death Cuts Efficiency.
+S M O K E R S   A R ....snip....  H   C U T S   E F F I C I E N C Y .
+s m o k e r s   a r ....snip....  b u t   d e a t h   c u t s...
+s m o k e r s   a r e   p r o d u c t i v e ,   b u t . . .
+s m o k e r s   a r e   p. . .
+```
+
+## Using modifiers in expressions
+
+Modifiers can also be used in expressions. For example, you can use the [isset modifier](./language-modifier-isset.md)
+to test if a variable holds a value different from null.
+
+```smarty
+{if $varA|isset}
+    <b>variable A is set</b>
+{/if}
+```
+
+You can also use modifiers in expressions in a PHP-style syntax:
+
+```smarty
+{if isset($varA)}
+    <b>variable A is set</b>
+{/if}
+```

+You may have noticed that the example template above renders the `$name` variable using

+modifier makes string 'safe' to use in the context of an HTML page.
+
+If you are primarily using Smarty for HTML-pages, it is recommended to enable automatic
+escaping. This way, you don't have to add `|escape` to every variable you use on a web page.
