  • How to make text bold in CSS
    How to make text bold in CSS
    To make web page text thicker, the most direct way is to use the font-weight attribute of CSS; 1. Basic writing methods such as p{font-weight:bold;} can make paragraph text bold; 2. This attribute supports keywords (such as normal, bold) and numerical values (such as 400 means normal, 700 means bold); 3. Use class names combined with HTML elements to achieve boldness of specific text, improving style reusability and code maintenance; 4. Note that not all fonts support multiple thickness settings, and some fonts such as handwritten fonts may only support fixed thickness, and compatibility needs to be confirmed through developer tools or font documents. Mastering font-weight can effectively enhance the visual hierarchy and reading experience of web pages.

    How to create a triangle with CSS?
    To create a CSS triangle, you need to use transparent border techniques: 1. Set the width to 0 and generate a triangle through the border. If the border-bottom is solid, the triangle will move upward; 2. Adjust the border width to control the size of the triangle, and the color is determined by the solid border; 3.

  • how to overlap elements in css
    how to overlap elements in css
    To achieve CSS element overlap, you need to use positioning and z-index to control the casing order. 1. Use position:relative, absolute or fixed to remove elements from normal document flow and position them; 2. Set the stacking level through the z-index attribute, the larger the value, the higher the forward, but only take effect on the positioning elements; 3. Common modes include card layout, corner badges, etc. Note that the parent container may create a new stacking context to affect the effect; 4. Simple overlap can be implemented with negative margins, such as margin-left:-20px for avatar or label stacking. Correctly understand the positioning, stacking context and z-index action mechanism to accurately control the overlapping effect.
