strong {color:#yourHexColour } Another example, not using hex colours; strong {color:blue} You may need to up the specificity though. Specificity is about being more precise when defining your css properties. For example, maybe the strong tag is inside a paragraph (it usually is); <p>lalalal <strong>this will be bold</strong> lalal </p> if you apply in the css; strong {color:blue} Then after write p {color:black} The paragraph will all be black. If however you do this: p strong {color:blue} p {color:black} You're being more specific by telling it each strong element inside the paragraph, is blue. Hope that helps.
