Introduction to the Topic
Selecting and placing the cursor within text on web pages is one of the interesting and functional possibilities that most websites utilize in their user experience. For example, it can be done by allowing users to select text or move the cursor between different text characters by clicking at different points. This topic is significant because it allows the user to interact with the existing text or information on the page.How to Implement
Despite the fact that the languages HTML and CSS do not provide native tools for controlling the cursor, you can implement this control by using JavaScript. Essentially, we should utilize JavaScript events to manage user clicks and handle them accordingly.Requirements
It is necessary to have a basic understanding of HTML and CSS. If you haven't worked with JavaScript yet, don't worry, the code provided below is relatively simple. Also, if you haven’t used JavaScript for a while, this topic may provide a good opportunity for you to practice.A Look at the Code
Now we will look at the specific code that implements this capability, so let’s take a look. Make sure that the code being used is applicable and usable.
<!DOCTYPE html>.

const range = document.createRange();
const sel = window.getSelection();
range.setStart(event.target, 1);
range.collapse(true);
sel.removeAllRanges();
sel.addRange(range);
});
</script>
