How can I design a circular textarea
where the text conforms to the shape?
Here is my attempt, but I'm unsure how to keep the text inside the circle without relying on javascript.
The concept of a "textarea with the shape of a circle and text fitting inside" may be open to interpretation. The solution provided here follows the standard rendering rules for a textarea
in HTML, allowing you to create a circular shape with text neatly contained within it. Achieving text in a truly circular form would require additional CSS properties like -webkit-shape-inside
.
By adjusting the padding appropriately:
textarea {
width: 500px;
height: 500px;
border-radius: 100%;
padding: 110px;
}
Check it out on jsFiddle: http://jsfiddle.net/zuh7z/8/
Here's the formula to calculate the necessary padding:
sqrt(2)*(width/2) - (width/2)
For our scenario where width = 500px:
required padding = sqrt(2)*(500/2) - (500/2)
= 353.55 - 250
= 103.55
Padding required: 103.55px
This innovative CSS3 feature is still in the experimental stage. For more information, check out: http://www.adobe.com/devnet/html5/articles/css3-regions.html.
Please note that this solution is currently only available on Chrome. To utilize it, you will need to activate the "Enable experimental WebKit features" flag in chrome://flags and then restart your browser.
Here's a fiddle showcasing this feature in action: http://jsfiddle.net/7JD9E/4/

CSS3:
textarea {
width: 500px;
height: 500px;
-webkit-shape-inside: circle(50%,50%,50%);
border-radius: 500px;
}
Here's a simple proof-of-concept you might find interesting:
The innovative concept involves replacing the textarea element with
<div contenteditable>
and using a clever technique to remove the curved part from text by employing a series of hidden floats of suitable dimensions.
However, utilizing this method requires determining the vertical position of the caret within the 'textarea' to avoid overflow issues, which may lead to a complex script resembling something out of NASA's playbook (I came across a related discussion on How to manage caret position in ContentEditable element? but struggled to adapt that solution to this specific scenario).
Perhaps incorporating a bit of padding could be beneficial?
textarea {
width: 350px;
height: 350px;
border-radius: 250px;
padding:75px;
}
You may have to experiment with the measurements though :)
Check out this awesome plugin. It is easy to use and can be customized to meet your specific needs.
Have you ever considered a unique method for creating a user-friendly text input? One idea is to utilize an innovative "NASA-like js" approach where a custom control made with SVG interacts with key events on a hidden textarea positioned behind it. By clicking on the control, the focus shifts to the textarea, allowing text to be entered and displayed within the SVG circle. This technique offers the advantage of presenting text within a circular clip area instead of a traditional square, enhancing the overall visual appeal.
While there may be some minor usability challenges to address, such as handling text selections through mouse or touch interactions, this concept is certainly achievable with some dedicated effort. The level of complexity ultimately depends on the amount of time and resources you are willing to invest in this project. :)
