 In this case, only links that contain both `href` and `title` attributes will be styled with green text. This level of control is what makes attribute selectors so powerful in CSS.
 
+Another example for an attribute selector is to match a single value within a space-separated list of values in an attribute.
+
+Here is an example of an anchor element with multiple classes:
+
+```html
+<a href="https://example.com" class="btn primary large">Visit Example Site</a>
+```
+
+To target this specific anchor element, you can use the following selector:
+
+```css
+a[class~="primary"] {
+  color: red;
+  font-weight: bold;
+}
+```
+
+The `[attr~=value]` syntax is used here to target all anchor elements where the class attribute contains the word `"primary"`.
+
+If you need to target an element where the attribute value is prefixed by a specific value, then you can use the `[attr^=value]` syntax. Here is an example:
+
+```css
+a[href^="https://"] {
+  color: green;
+  text-decoration: underline;
+}
+```
+
+In this example, the `a[href^="https://"]` selector will target all anchor elements where the `href` attribute value starts with `"https://"`. 
+
+To target elements where the attribute value ends with a specific value, you can use the `[attr$=value]` syntax. Here is an example:
+
+```css
+a[href$=".jpg"] {
+  color: darkgreen;
+  text-decoration: underline dotted;
+}
+```
+
+In this example, the `a[href$=".jpg"]` selector will target all anchor elements where the `href` attribute value ends with `.jpg`. 
+
 Using attribute selectors not only enhances the styling of your webpage but also improves accessibility by making interactive elements like links more distinguishable based on their attributes.
