How to add a watermark in Photoshop
Article Introduction：There are three main ways to add watermarks in Photoshop, namely text watermark, image watermark and batch processing. 1. When adding text watermarks, use the text tool to enter the content and adjust the font, size and color. It is recommended to set it to light gray or white translucent, with the opacity set to about 50%, and place it in the corner of the picture to avoid interference with the subject; 2. When using image watermarks, you need to prepare a transparent background image in PNG format. After dragging it into the document, you need to adjust the size, position and transparency, be careful not to block the main content; 3. Adding watermarks in batches can record the operation process of adding watermarks through the "action" function, and then automatically apply it to multiple files through the "batch" function. The key to improving efficiency is to prepare a unified watermark template in advance.

how to add a watermark in Premiere Pro

Import the image as a layer and adjust the position, size and transparency (PNG format is recommended); 2.

How do you add a CSS class to a DOM element using JavaScript?
Article Introduction：The best way to add a CSS class to a DOM element using JavaScript is through classList.add(). 1. Use the element.classList.add() method to safely add one or more classes to elements. If the class already exists, it will not be added repeatedly, such as myElement.classList.add('new-class') or add multiple classes at the same time myElement.classList.add('class1','class2','class3'). 2. You can use the className attribute to modify the class name, but the direct assignment will overwrite the original class name, and splicing strings will easily lead to heavy spaces.

php add hours to datetime
Article Introduction：In PHP, you can add hours to date and time by using the DateTime class with the modify() or add() method. Use the modify() method to pass in string parameters similar to '3hours' to directly modify the original object, which is suitable for simple adjustment; if you do not want to change the original object, you need to clone it before operating; use the add() method, you need to cooperate with the DateInterval object, such as 'PT2H', which means adding two hours, which is more suitable for structured development; when processing time zones, DateTimeZone should be set to ensure accuracy; for old versions of PHP, you can use strtotime() to implement it, but it is not recommended for complex logic.
