STEPS:

I have created a simple custom list and name it as ‘My List‘

Modified the ‘Title‘ column name as ‘Student Name‘

Created one more column ‘Subject‘ which is of type single line text

Also, created one column ‘Marks‘ which is of type Number min is 1 and max is 100

Open the AllItems.aspx page using Sharepoint Designer 2007

Select the list, right click and Convert into XSLT mode

Write the XSL condition in between the ‘Subject‘ TD tag as show in the below image

Here goes the XSL code……

<!–custom code for background color starts–>

<xsl:choose>
<xsl:when test=”@Marks &gt;=’70′”>
<xsl:attribute name=”style”>background-color:Green;</xsl:attribute>
</xsl:when>
<xsl:when test=”@Marks &lt;=’70′ and @Marks &gt;=’50′”>
<xsl:attribute name=”style”>background-color:Yellow;</xsl:attribute>
</xsl:when>
<xsl:otherwise>
<xsl:attribute name=”style”>background-color:Red;</xsl:attribute>
</xsl:otherwise>
</xsl:choose>

XSL condition in Sharepoint Designer 2007

Output:

Background color to Sharepoint Custom List column based on Marks
