Decorating Heading Tags

This help article describes the important changes of RadFormDecorator in Lightweight mode that come with the Q3 2015 release.

  1. Heading Stylization Cascades Through Individual Classes

  2. Heading Default Font-size Metric is Changed from PX to EM

  3. Heading Tags with Custom Classes will not be Decorated

Heading Stylization Cascades Through Individual Classes

RadFormDecorator in Lightweight will not add a global rfdHeading class to the HTML tag anymore. From this time onwards, the CSS class rfdHeading will be added to each heading tag. You can find the DOM structure of decorated H4, H5 and H6 tags prior and after the change in Example 1 and Example 2.

Example 1: Heading tags are styled by RadFormDecorator through a global class, added to the HTML tag prior to the Q3 2015 release.

<html class="RadForm RadForm_Default rfdHeading rfdRoundedCorners" xmlns="http://www.w3.org/1999/xhtml">
...
    <h4>Heading 4</h4>
    <h5>Heading 5</h5>
    <h6>Heading 6</h6>
...
</html>

Example 2: Heading tags have been styled by RadFormDecorator through an individual class, added to each heading tag since the Q3 2015 release.

<html class="RadForm RadForm_Default rfdRoundedCorners" xmlns="http://www.w3.org/1999/xhtml">
...
    <h4 class="rfdHeading">Heading 4</h4>
    <h5 class="rfdHeading">Heading 5</h5>
    <h6 class="rfdHeading">Heading 6</h6>
..
</html>

This change will affect any custom styles or skin customizations related to heading tags decoration. You should change the old selectors from Example 3 to match the new ones from Example 4.

Example 3: RadFormDecorator old selectors for decorating heading tags with the Default skin.

.RadForm.rfdHeading h4 {
    font-size: 14px;
}
.RadForm.rfdHeading h5 {
    font-size: 13px;
}
.RadForm.rfdHeading h6 {
    font-size: 12px;
}

.RadForm_Default.RadForm.rfdHeading h4, 
.RadForm_Default.RadForm.rfdHeading h5, 
.RadForm_Default.RadForm.rfdHeading h6 {
    color: #333;
}
.RadForm_Default.rfdHeading h4, 
.RadForm_Default.rfdHeading h5, 
.RadForm_Default.rfdHeading h6 {
    border-bottom-color: #8a8a8a;
}

.RadForm.rfdHeading h4, 
.RadForm.rfdHeading h5, 
.RadForm.rfdHeading h6 {
    border-bottom-style: solid;
    border-bottom-width: 1px;
    font-weight: normal;
    line-height: normal;
    margin: 0.83333em 0;
    padding: 0.16667em 0;
}

Example 4: RadFormDecorator new selectors for decorating heading tags with the Default skin.

.RadForm h4.rfdHeading {
    font-size: 1.16667em;
}
.RadForm h5.rfdHeading {
    font-size: 1.08333em;
}
.RadForm h6.rfdHeading {
    font-size: 1em;
}

RadForm_Default .rfdHeading {
    color: #333333;
}

.RadForm_Default .rfdHeading {
    border-bottom-color: #8a8a8a;
}
.RadForm .rfdHeading {
    border-bottom-style: solid;
    border-bottom-width: 1px;
    font-weight: normal;
    line-height: normal;
    margin: 0.83333em 0;
    padding: 0.16667em 0;
}

Heading Default Font-size Metric is Changed from PX to EM

The default font-size metrics of decorated heading tags are changed from px to em (Example 3 and Example 4). This change is required to create an elastic design for the control.

Heading Tags with Custom Classes will not be Decorated

When a custom class is applied to a heading tag it will be perceived as a customly styled element and hence RadFormDecorator will skip it from decoration. This behavior also resolves styles overriding issues when RadFormDecorator is integrated with other controls from the Telerik® UI for ASP.NET Ajax suite.
